Kilometers to miles is probably the easiest common conversion. 5 km is 3 miles, easy peasy.

Are we talking about British, American or sea miles?

kilometers to nautical miles are easier tbf

Except 5km is not 3 miles... it's 3.1069 miles so off by a considerable factor. 1 mile = 1.6km is a much more accurate approximation that's easy to remember.

That's 4%, that's not a significant amount for functional purposes and it's a whole number to whole number conversion. Most of the time, if I'm converting, it's from metric to imperial so 1 km is 0.62 miles. If you tell me the speed limit is 70 km/h it's way easier for me to calculate 70 ÷ 5 x 3 = 42 mph than to calculate either 0.62 x 70 or 70 ÷ 1.6 = 43.49.

A mile is 8 furlongs.
