In Physical Constants Package (I know it's obsolete now, still handy) when I call a constant and do some manipulations I am left with something that has units attached to it. How can I remove this units part leaving just the number? Thanks.
Thanks, that works.
The best choice to do what you want is by using the functions Quantity, UnitConvert and QuantityMagnitude.
If you do not want or cannot use them for some reason, one possible way to get the numerical value from the measurement is by using Part or First.
%% // First
