A student exercise: It starts with a defintion D1 := 1.500*Unit('m') and ends (after some calculations) with the following expression:
I would like to simplify it to get -0.0175 m^3, but I get the following error when I try to simplify the units: Error, (in Units:-Standard:-+) the units `m` and `1/m` have incompatible dimensions.
This makes no sense! All calculations are based on the initial definition of D1, which is the only input unit.
Why do I get this error?
