Actual poster from 1917 that made me laugh. A lot.
Also, those motherfuckers are measuring the weight of those balls in kilograms, aren’t they?

One mile is 5280 feet, one foot is 12 inches. One square foot is 144 square inches, one cubic foot is 1728 cubic inches.
1 gallon of water is 8.34 pounds, and 1 cubic foot is 7.48 gallons, so a cubic foot of water weighs 62.38 pounds. If sand is 2.3 times heavier than water, a cubic foot of sand weighs 143.5 pounds.
I am 5 feet 10 inches tall, or 5.83 feet, or 70 inches. I weigh about 220 pounds, or 3520 ounces. If I’m 65% water, I carry about 143 pounds of water, or a little over 16 gallons.
Guh
Bit silly to mix decimal with non-base 10 measurements!
It’s worse than that. Inches are base 12, ounces and cups are base 16, machinists use thousandths of an inch, and surveyors use tenths of a foot!
And computers use base 2. Bastards.
I had to check the math because 1 m2 being 2300 kg while 1 cu ft at 143 lbs seemed crazy, but with the volume difference it’s all correct.
Thank you for putting in the effort 🙃
To illustrate, 1m³ = (100cm)³ = 1,000,000cm³ = (1000mm)³ = 1,000,000,000mm³
You go from the single dimensional conversion between m and cm being a factor of 100 and 1000 for m and mm, to the 3 dimensional conversion being a factor of 1 million for m and cm or 1 billion for m and mm. It scales up fast.
That was totally logical to me
Cool.
Also great way to miss the point. And great use of your calculator. The entire thing is that the metric system is not just “arbitrary amounts”, it’s all designed to fit together easily.
Now, no calculator. How many feet is 0.683 miles?
I know that 0.683 kilometers is 683 meters.
