How do you convert height to miles?

Answer 1

You need to specify the height of what.

height can be messured in the same manner as length. i.e. something that is 5280 feet high is one mile high. Therefore an item at 10,000 feet above ground at one fixed point it can be said to be 1.89 miles high.

The calculation is e.g. 10,000(feet) divided by 5280.00(feet) = 1.89 miles.

If the height is in yards then its 333.333 yards high divided by 1760.00(yards in a mile) = 1 (mile)

However, if you are looking at converting aircraft height and not building heights then The nautical mile (symbol NM ) is a unit of length that is about one minute of arc of latitude measured along any meridian, or about one minute of arc of longitude at the equator. By international agreement it has been set at 1,852 metres exactly (about 6,076 feet).

e.g 1 foot = 0.000164579 nautical miles

1000 feet = 0.164579 NM

10,000 feet = 1.164579 NM
