It actually works pretty well by chance more than anything else. 1000 ft is a really good altitude separation between aircraft. 500 is a good offset for irregular traffic too. Multiples of 150/300 m are more annoying to work with and 500/1000 m would waste an excessively large amount of airspace.

It gets even more interesting when aviation uses:

Tho relationship of nautical miles and knots for speed is really good for navigating over a sphere. There are some handy shortcuts that make quick mental calculations fast and intuitive, specially with an e6b flight computer (not an electronic).
The alternative would’ve been to use euclidean planes, projections and radian transformations, which would’ve been harder to use for navigating.

not really. distance is measured in (nautical) miles, speed in knots (1 knot is 1 nautical mile per hour)
