I am implementing a model defined with quantity data having {value, multiplier, unit} where multiplier is m, c, k, M, etc unit is V, A, Hz, W, etc

So I am looking for what quantities/units packages are around before trying to write my own.

I have downloaded [1] and had a poke around there with the tests. Are there any further examples around of how to use it and to define new units? I notice that Voltage=Joules/Columb is not defined.

Is anyone have any familiar with ports of packages mentioned here [2] [3] [4] from other platforms?

cheers, Ben
