I list these in no particular preference, as the previous poster commented you will need a precision mechanical balance or similar resolution digital scale.
I have used these formulae with good results, but prefer the comercial dev's for my professional work.

I have several others that may be of interest to you, but these are the ones that I have used in the past, note once mixed, none of these will keep very long.
