rad2sm

Convert spherical distance from radians to statute miles

Syntax

sm = rad2sm(rad)
sm = rad2sm(rad,radius)
sm = rad2sm(rad,sphere)

Description

sm = rad2sm(rad) converts distances from radians to statute miles as measured along a great circle on a sphere with a radius of 6371 km, the mean radius of the Earth.

sm = rad2sm(rad,radius) converts distances from radians to statute miles as measured along a great circle on a sphere having the specified radius. radius must be in units of statute miles.

sm = rad2sm(rad,sphere) converts distances from radians to statute miles, as measured along a great circle on a sphere approximating an object in the Solar System. sphere may be one of the following: 'sun', 'moon', 'mercury', 'venus', 'earth', 'mars', 'jupiter', 'saturn', 'uranus', 'neptune', or 'pluto', and is case-insensitive.

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
