Petro Unit Converter at Mac App Store analyse

Petro Unit Converter is a useful utility for converting oil and gas exploration and production related units between SI and M. The conversions included are; temperature, thermal gradient, GOR "Gas oil ratio", oil gravity, Vs from Vp, sonic slowness and velocity, area, volume, pressure, pressure gradient and salinity. All the conversion are found on the internet but I find it is useful to have a standalone app that contains these conversions without having to have a browser open.
