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.

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 m^2^ 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.

Cool.

Also great way to miss the point.

Now, no calculator. How many feet is 0.683 miles?

I know that 0.683 kilometers is 683 meters.
