Can Mathematical constants be defined with units similar to physical constants? Example  PI Thanks & Regards, Prashant S Akerkar

I have found it occasionally useful to put a unit on some quantities which have no unit, similar to the radians case. For example when doing a complicated problem I have noted that we can define a "unit" for a variable, x for example, which I would call "x ness." The x ness of an expression should be the same at the start of the problem as it is in the end. It doesn't always work but I've found that it makes a convenient check to see if I've done the problem correctly. Dan

If you can prove changing $\pi$ with $1$ dosen't effect the result in your problem, than $\pi$ (or else) can be your unit of measure. As example in the geometric problems it can be the common "tessel" that can be used to fullfit all the Areas you've in the problem, etc...
