Conversion from MG/ML to %

[pye]

First of all, great package! I am not sure if this is the right place to report issue here. But I notice that conversion from MG/ML (usually used in RxNorm, eg. rxcui 861487) to % is giving the incorrect result as

0.5 mg/mL = 50000.00 %

The correct result should be 0.05 %

Thanks!

It seems that in drug, the concentration is assumed to be calculated in water so MG/ML would be MG/G. but since ucum does not assume that this conversion might not be valid so might as well throw an error.

Thanks for reporting this issue. It seems that using mg/g does give the expected 0.05 %. I would have expected mg/mL report an error because strictly speaking it does not have the same dimensions as %. Anyway, we will look into it, but probably will report an error rather than handling mL->g implicit conversions. Are you able to work around the issue by using mg/g?
