If you work in a biochemistry lab, you will find this App indispensable! Enter any three of the unit groups: (gm, mg, ug), (M, mM, uM, nM), (L, mL, uL), or (MW) and the fourth is instantly presented. This app is simple, quick and easy to use, and that’s exactly what makes it a productive tool. Enter any three unit-measures, in any order, and you have your answer. I’ve spent over 15 years working in the biotechnology industry, and this App has been a huge time saver - and it never makes mistakes!
