Metric

This made me laugh out loud! I know it’s silly. I also much prefer the metric system (actually, SI more generally). But sill...

I think there is one other nation that uses the Inch or English system of measurement. Actually, I think the US Officially is metric. Just doesn't use it. I go back and forth at work between Inch and Metric. Its much better with Metric. Also, for press fits, I think the Metric specs are better. Still, the pic is funny. Could say WW2 was won by the Inch.

Id be curious (but not enough to google it for myself)...

THe engineers that designed the rockets and such that took us to the moon, did they use inches/lbs/ft on their drawings ?

Canada is officially metric. America is not unless things have changed. We have a mixed system but over time metric is becoming predominate in Canada.

I used to get a lot of questions about conversions of one to the other for years. This seldom occurs now.

Metric

All this talk about US Versus Metric, my wife is liable to figure out what 6" is!

Weird is that Great Britain uses “metric”, but speed limits are shown in miles per hour. Beer is served in pints. Petrol is sold in liters.

Post Metrics

Yes, that's a good funny .

America went over to the metric system long ago, I no longer work on new cars but I *think* they dropped it after a few years, for a long time there were "METRIC" decals or embossings on units (trannies and so on) to warn the hapless Mechanic .

I prefer the Metric system but grew up with the inch and am happy with that too .

As long as we all can laugh about it, it's good .

I have Russian Motocycles that are Metric but wow, the quality control is all over the map .

I toured an ex Russian submarine once, it was scary ~ the welds looked so crappy I'd be afraid to go across a lake in it .

It had windows in the conning tower too, how odd .

Sounds far more impressive when described in centimeters?


Not that guys lie. If you ask almost any woman to indicate a space of twelve inches between their index fingers. For some unknown reason it tends to be far less than the reality.

I prefer metric. It would be nice to only buy metric tools instead of Wasting money buying 2 sets. That’s a nice lil scam The tool companies have going

It's not any scam .

You also forgot the dreaded and wretched Whitworth system....

Feet and inches are more sensible. What isn't sensible is the decimal system. Duodecimal (base 12) is the natural counting system for humans. That's why 12 hours in a day, 12 in a dozen, 12 eggs in a box, 360 degree in a circle, 60 minutes in an hour. There's a reason why so many of our measurements are base 12.

First, where it comes from. Hold up your hand. Using your thumb, count the joints on your four fingers. 12. it's faster to count on your joints, and you can count higher. From there, accumulate 12's on your other hand. You can accumulate five 12's, or 60. Or you can accumulate 12 12's, or 144.

This system of counting goes back at least to the Babylonians. It was used by the Egyptians and Greeks. The Romans weren't 'rithmetricians, and had their own oddball system. But they used the Greek methods of counting for any serious engineering or accounting. Finger counting systems based on duodecimal arithmetic became very sophisticated, and there's a method of duodecimal finger computation that is similar to an abacus. For larger sums, a stone table with reliefs for each digit was used in conjunction with differnt color pebbles for counting and computation. Thus our word "counter", and the greek word "trapeza" (bank).

This world pretty much evaporated in the dark ages, during which Europe managed to unlearn two millenia of mathematics. During the late middle ages, arithmetic was gradually reintroduced from India by way of Arab traders. The indians used the decimal system, augmented by the invention of zero. Which sounds odd, but you can't count to zero on your fingers. So it's not an intuitive idea. Classical mathematics survived only in measurement systems, while the usurping decimal system conquered the western world.

So I'm all for metrication, but based on duodecimal. Bring back the classics. The only other alternative is to decimalize time and triangles, to be consistent

Buying two sets of crescent wrenches is a pain.

Your observation may explain why base twelve was adopted by the earliest Mesopotamian cultures. Planetary astronomy really messed with their heads. It almost works to divide 365 by 12 and get 30 days, which is close to the lunar cycle and the lunar cycle is dead-on for the average human menstrual cycle.

DMS is great for plain geometry but once you get into calculus you drop that shyte quick and go full-on radian.
