  1. 2:43 There is a version of this need for unit conversion still relevant today. And that has to do with angles. Because most of us cope more intuitively with angles measured in degrees (or even fractions of a circle) than in radians, whereas most trigonometric calculations are most naturally done in radians. So it makes sense to store angles internally in radians, while letting the user see (and input) them in a choice of units.

  2. What really baffles me, watching/hearing/reading records of the Apollo missions, is how they randomly switch between different units, such as mph versus knots versus miles per second. Couldn’t they at least forego the nautical miles and stick to statute miles?

  3. 6:49 Actually, computers have unit-calculation apps available -- at least in all the self-respecting OSes -- that can cope with such common tasks. Such as this one https://www.gnu.org/software/units/ .

  4. 8:41 There is a unit called the “poundal” for force/weight, distinct from “pound” for mass.

  5.  @Mortlupo  Spacecraft most certainly do not use knots. Remember, nearly all such missions are international nowadays, and it’s all metric out there. And there are places even within our atmosphere where aircraft are controlled using SI units.

  6. So, instead of multiplying by 0.3937..., just divide by 2.54.

  7. You can do measurements without errors? Or, just stick to rational arithmetic, then.

  8.  @CaptainDangeax  Use exact rational arithmetic, if that’s what you want.

  9. 0:55 Countries that have landed on the Moon also include the USSR/Russia, and now China and India. So those using Imperial are already outnumbered there as well.
