Who in gods name looks at imperial and goes "yeah that's completely logical and straightforward"

Eta: also no, the arrows are not wrong.

1km x 1000 = 1000m

E: When you are converting units, the units themselves are involved in the equation (think of it like ""kilometer = y"");

(1000 meters/1 kilometer) × (1 kilometer/1) = 1000 meters.

The "kilometer" cancel eachother out.

Base ten isn't fantastic for fractions, particularly back in the day. Customary systems worked pretty well before precise measurements and easy calculating became common.

Edit: please read carefully. A lot of people seem to think I'm bashing the Metric system or something.

So, they're making the argument that everyone should switch to metric. Just because once horses were the best way of getting around fast, doesn't mean that it's still a good idea to use a horse to get somewhere.

I think the other dude is trying to point out that base 10 is used only because we have 10 digits on each of our arm hands/feet.

Though from a purely mathematical view we may have been quicker with math problems had we used base 12 from the start, due to 12 being divisible by 1,2,3,4,6,12, and 10 only being divisible by 1,2,5,10.

There would be two extra symbols to learn but fractions would be more easily represented, and would be saving on space since fewer symbols are needed.

Moreso, our months and hours already number 1 to 12, our minutes and seconds already number 1 to 60, and our degrees 1 to 360.

All this has nothing to do with customary conversions, but just pointing out that usage of base 12 is closer than you think!

He's just pointing out that it was useful back in the day, no need to be so snarky dude. Yeah, metric is far more useful and intuitive to us today but traditions die hard.

Imperial units were useful for dividing things evenly. 1000 has 1 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500,and 1000 as factors, most of which are only easily dividable by 5 and 10. 1760 has 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 32, 40, 44, 55, 80, 88, 110, 160, 176, 220, 352, 440, 880 as factors, many of which can be divided by many of the others.

Again, just because something is better doesn't mean it's going to be easy for everyone to move to it right away. Base 12 is better than base 10 in a lot of ways and is more natural to human instinct, I doubt that's going to make you use it. Likewise I live in a country that did switch from Imperial measurements to Metric in terms of roadsigns and cars and a lot of people still informally use miles.

I_kwote_TheOffice

18 points

This is a really good point. There are tons of information about why Base 12 is better than Base 10. In fact, I believe there was a movement a long time ago to move from base 10 to base 12, which would then make the metric system completely different. That idea was shot down. I'm not going to pretend like Imperial/Standard/American system is better than metric. There are a few advantages that it has over metric, but metric is almost objectively better in so many ways. But the irony is that metric (or whatever the name would have been in base 12) could have been even better if it used base 12, and metric proponents often ridicule Americans for not switching to a better system.

I have the opposite take of of you. The US has adopted a system that evolved from the bottom up, naturally over millennia, which reflects the nature of a heavily decentralized republic and the concept of spontaneous order. The metric system is a top down implementation, which reflects the nature of governments in countries who are used to having strong central control over their citizens.

The factors of 12 are: 1, 2, 3, 4, 6, and 12. I'm not saying imperial is better, but you do end up with whole numbers more often when you divide 12 as opposed to 10.

terrybrugehiplo

It’s not really about freedom units being better, it’s about familiarity. If you say; foot, yard, mile.. I immediately understand the distance because it’s ingrained into my head since childhood.

Substitute that for Metric and it’s a foreign measurement that rarely used so you have to think about it a little more, that’s all.

Also, I rarely ever need to know how many feet are in a mile. It almost never comes up in my life. So conversions being easier for metric doesn’t even matter. If someone was like “I live 10 miles down the road” I’m not ever going “yeah but how many feet is that?”

The conversion benefit of metric is rarely used in daily life, so it’s irrelevant for most people

The thing is you don’t really convert the units, except rarely. If you’re talking about travel it’s always miles or fractions of miles. Yards are rare, and mostly used in sports. The exception is feet and inches. Measurements are usually described in terms of both together (3 ft 2 in).

Just because it’s not conducive to base 10 numbering doesn’t make it illogical. It’s just different than what you’re used to.

And the thing about 12 is you have an easier time dividing it as there are more factors. You have easy division into 1/2, 1/3, 1/4, 1/6, and thus 2/3, 3/4, are also very easy.

Plus an inch is slightly more than 25mm, and in an era pre machine precision half an inch, or half of that, a quarter inch, or half again, an eighth, or half again, a 16th, would be easier to understand than 1.5875mm. Imperial only requires the ability to half something, metric requires 4 decimal places of precision.

The thing about Imperial is that it's not meant to be logical. No one sat down and said "Gee whiz, let's put 5280 feet in a mile to confuse people". They come from traditional measurements based on more natural ideas.

What is a meter? Sure, if you have a meter stick or ruler you can accurately count a meter, but plop a person down in the middle of a deserted island and it just doesn't make sense to use meters.

A foot is, logically, roughly the size of a foot (similar to cubits being the length of the forearm); a mile comes from Rome and is basically 1000 paces (and was used to denote distance for the Roman legions on campaign); an acre is the amount of field a man can reasonably expect to plow in a working day; etc etc.

To add to that, you wouldn't really cross over measurements that much. A foot is a foot long, and a mile is a mile long. When would the average person need to measure the length of distance between two points more than a few feet long? Even farming has it's own system of acres and most likely was mapped out long before anyone ever tilled the soil (and generations would work on the same farm). Natural borders are easier to use, "You have that piece of land down to the river, and we'll use this hedgerow to divide our lots".

That's also to mention that before the industrial era, you didn't really need to be able to accurately measure distance down to the centimeter. The metric system is useful to us in the modern day who need to be able to tell distance accurately, and have the tools to do so, but IMHO trying to say "Oh, look at how stupid those people were for not using what we use" is kinda like mocking people for using horses when they could've just invented the combustion engine. It's a combination of what was useful for their needs, and what was in their ability to measure.

Ofc, I'm in favour of using metric today but y'know I'm not American so I already do.

EDIT: corrected the amount of feets in a mile because I'm a filthy European who grew up with glorious meters

To be fair there are practical advantages to some of the units. 12 inches to the foot means it can be divided cleanly by 2, 3, 4 and 6 while base 10 in metric only has 2 and 5.

Base 12 should have been used for metric and forced on the world.

Nah but many Americans think the USA is the entire world and they are the main character of the world.

The implication that no one outside of the United States is arrogant is something that just screams "I'm an American who has never left the country."

I was high on shrooms one night making paper airplanes and the guide said "measure two and a half inches from the peak and valley fold" and I screamed "my kingdom for an imperial ruler!" and nobody else got the joke.

You're reading it wrong. The guide is saying multiply by 12 to get the amount in inches

1 foot x 12 = 12 inches.

When I was in school we were not taught yards, I played football and never knew it was exactly 3ft. I just thought it was the however far between the hashes on the field. Didn't really figure it out till I was in my 20's.

You are wrong. An inch is divided into 8, 16, or 32 units depending on how precise you need to be.1/8, 1/16, 1/32, etc.

The good about metric is that you don't need these conversion aids... you just look at the letter before the 'm' and replace it with the corresponding power of ten

Metric prefix

A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic. Each prefix has a unique symbol that is prepended to any unit symbol. The prefix kilo-, for example, may be added to gram to indicate multiplication by one thousand: one kilogram is equal to one thousand grams.

km, k=1000, so km is 1000m

cm, c=1/100, so cm is 0.01m

mm, m=1/1000, so mm is 0.001m

km, k = kilo = 1000. cm, c = cent = (like in money) 100 cents = 1 €/$. works pretty well

Well we have nano, micro, milli, centi, deci and kilo for example.

To say 1 nanometer you could either write 1nm or 1m * 10-9 . The rest of them would be

1μm = 1m * 10^-6

1mm = 1m * 10^-3

1cm = 1m * 10^-2

1dm = 1m * 10^-1

1m = 1m *10^0

1km = 1m * 10^3

It all depends on what your used to. First, I’ve never needed to convert between miles and yards. Second. I almost never use yards. Literally the only times I use yards is for ordering dirt/gravel/compost/etc. which is sold by the cubic yard. I certainly never convert between miles and yards and yards and feet. What possible use case could there be? Finally, a foot is just 12 inches. This one I use all the time as a woodworker. I want to divide something into thirds, it’s 3x4 inches. Into fourths, it’s 4x3 inches. In half, it’s 2x6 inches. Into sixths, it’s 6x2 inches. Etc.

I know the point of this is to show how complicated imperial is supposed to be, but the reality is when you grow up with it, it is easy and natural. On a day to day basis, you only use miles for driving and feet/inches for everything else. And you never convert between anything except for inches and feet. What’s the point?

I've grown up with imperial and took shop classes through HS and I still can't understand the system. If I'm drawing out a little hobby build I'll first sketch everything out in metric and then cover over when buying materials

irrational_design

This confuses me. Basically all materials you would build with are in imperial. All lumber is imperial (inches and feet), most hardware is imperial (inches), etc. And they are designed to go together. Walls are designed around 8 foot lengths. If you are using metric and convert, it’s doubtful it will end up as 8 feet.

When you grow up with anything, it seems easy and natural even though another way could actually be easier and more natural if you tried it out long enough. The whole basis behind progressivism vs conservatism. One group is looking for better ways, the other just wants to do what it was doing before and fight any sort of positive change. It's more emotional than rational

Real progress would be changing the length of a meter ever so slightly so that the speed of light is exactly 300,000 m/second.

They are like the odd members off family who are outshined by their siblings. For real though, as 1m is the base unit, they are just too close too be more exact/accurate.

I've never used decimeter or decameter ever since we learned the terms in 5th grade or so. Anything that could sensibly be converted to decimeter or decameter can just as well be displayed as centimeters or meters, so I guess it settled on increments of 10^3

Perhaps it’s early and I haven’t had enough coffee, but isn’t the customary image arrows facing the wrong direction? As it reads, to get from inch to a foot you divide by 12, whereas in fact to get from inch to foot you multiply by 12. Seems like the arrows are backwards.

ITT, Brits feeling superior when they didn't personally do anything at all. You were born in a country that uses metric, you were forced to use metric, you didn't invent metric. Yes metric is better.

I was born in the united states. I did not invent imperial. I did not choose imperial, I am not an idiot because miles exist.

Please, for the love of god, fuck off with this endless rhetoric. You are not superior to me.

Yards Aren't supposed to be converted to miles.

The original mile was 1,000 paces. Since people, you know, walked everywhere.

And the yard was a measure of cloth. Not distance.

What really confuses me about metric is why the speed of light is not 300,000 meters per second. That’s a huge miss. It is so obvious to tie it to the ultimate speed limit.

therealtheremin

You’d prefer if they redefined the almost perfect units of measurement that accurately measure our immediate surroundings on earth, so that we have a nice round figure for an abstract conceptualisation of the speed of light as the basis from which all other measurements are divided and in reference to? Are you American?

Metric is also based on water.

1ml of water is 1cm cubed

1litre of water is 1kg

0°C is freezing temperature and 100°C is the boiling point

1 calorie is enough energy to heat 1 gram (1ml) of water by 1°C

US Customary Units, not Imperial

NewAnon722

The customary method is not as easy to use but it's still pretty important. Its old but it's used to compare the measure of man to the measure of earth and does actually make sense if you know why it was made the way it is. The inch is an average human digit (finger segment) a foot was..well a foot. 2 yards was average height. A NAUTICAL mile is proportional to the circumference of the earth (1/60th of a degree of 360 degrees). A regular mile is smaller because the circumference gets smaller the further you get from the equator but its essentially has the same use as a nautical miles but works better to measure circumference in Europe's longitude.

It was really important back in the day when we were still measuring the heavens and the body of earth and trying to understand our relation to and place among them. These measurements were hella important to freemasons who basically planned and built America's foundation too. It would be sad if the system disappeared.
