Is it possible to convert between nautical miles and arc length in degrees using the UNITSRATIO function within the Mapping Toolbox 2.5 (R2007a) ?

When I try to convert between nautical miles on the Earth's surface and arc length in degrees:

unitsratio('m','deg')

I receive the following result:

 ??? Error using ==> unitsratio at 152

 Unable to convert to m from deg.

The ability to convert between arc length in degrees and length units such as nautical miles is not available from within UNITSRATIO in the Mapping Toolbox 2.5 (R2007a).

To work around this issue, use the DEG2NM and NM2DEG functions within the Mapping Toolbox:

deg2nm(1)
