Problem 1307

Summary:	degrees defined incorrectly in G4SIunits.h

Description Brett Viren 2012-04-25 18:55:38 CEST

In geant4.9.5.p01 I happen to be looking at G4SIunits and see that the "degree" definition is inverted from what is correct:

static const double degree = (3.14159265358979323846/180.0)*radian;

It looks like G4SIunits.hh are not used in the rest of the G4 source so this is only a potential problem but may bite someone someday if not fixed.

The definition of 'degree' in G4SIUnits (and in CLHEP) is correct, as it relies upon transformation from radians, where 'radian' is considered as unit.
