deg2km, deg2nm, deg2sm - Convert distance from degrees to kilometers, nautical miles, or statute miles

Syntax

km = deg2km(deg)
nm = deg2nm(deg)
sm = deg2sm(deg)
km = deg2km(deg,radius)
nm = deg2nm(deg,radius)
sm = deg2sm(deg,radius)
km = deg2km(deg,sphere)
nm = deg2nm(deg,sphere)
sm = deg2sm(deg,sphere)

Description

km = deg2km(deg) converts distances from degrees to kilometers as measured along a great circle on a sphere with a radius of 6371 km, the mean radius of the Earth.

nm = deg2nm(deg) and sm = deg2sm(deg) work identically, except that the output units are nautical miles and statute miles, respectively.

km = deg2km(deg,radius) converts distances from degrees to kilometers as measured along a great circle on a sphere having the specified radius. radius must be in units of kilometers.

For nm = deg2nm(deg,radius) and sm = deg2sm(deg,radius), make sure your input radius is in the appropriate units.

km = deg2km(deg,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 = deg2nm(deg,sphere) and sm = deg2sm(deg,sphere) work identically, except that the output units are nautical miles and statute miles, respectively.

Examples

A degree of arc length is about 60 nautical miles:

deg2nm(1)

ans =
   60.0405

This is not true on Mercury, of course:

deg2nm(1,'mercury')

ans =
   22.9852
