# Radiandegree conversion

Hello,

It seems to be unnecessarily hard to numerically convert radians to degrees in Sage. For example, how does one convert arctan(4/5) radians to degrees?

The following

n(arctan(4/5))*sage.symbolic.units.convert(units.angles.radian,units.angles.degree)

returns

121.453369600239*degree/pi

Is there a simple way to just return a numerical answer (without multiplying by 180/pi)?

What is wrong with multiplying by 180/pi ?

I just wanted to see if it could be done with Sage's units module.
