rad2km, rad2nm, rad2sm - Convert distance from radians to kilometers, nautical miles, or statute miles

Syntax

km = rad2km(rad)
nm = rad2nm(rad)
sm = rad2sm(rad)
km = rad2km(rad,radius)
nm = rad2nm(rad,radius)
sm = rad2sm(rad,radius)
km = rad2km(rad,sphere)
nm = rad2nm(rad,sphere)
sm = rad2sm(rad,sphere)

Description

km = rad2km(rad) converts distances from radians to kilometers as measured along a great circle on a sphere with a radius of 6371 km, the mean radius of the Earth.

nm = rad2nm(rad) and sm = rad2sm(rad) work identically, except that the output units are nautical miles and statute miles, respectively.

km = rad2km(rad,radius) converts distances from radians to kilometers as measured along a great circle on a sphere having the specified radius. radius must be in units of kilometers.

For nm = rad2nm(rad,radius) and sm = rad2sm(rad,radius), make sure your input radius is in the appropriate units.

km = rad2km(rad,sphere) converts distances from degrees to kilometers, as measured along a great circle on a sphere approximating an object in the Solar System. sphere may be one of the following strings: 'sun', 'moon', 'mercury', 'venus', 'earth', 'mars', 'jupiter', 'saturn', 'uranus', 'neptune', or 'pluto', and is case-insensitive.

nm = rad2nm(rad,sphere) and sm = rad2sm(rad,sphere) work identically, except that the output units are nautical miles and statute miles, respectively.

Examples

How long is a trip around the equator in statute miles?

sm = rad2sm(2*pi)

sm =
   2.4874e+04

How about on Jupiter?

sm = rad2sm(2*pi,'jupiter')

sm =
   2.7283e+005
