Engineering units, instantly.

Every unit conversion an oil and gas process engineer needs – pressure, flow, viscosity, gas volumes, and the ones textbooks always get wrong (psig vs psia, MMSCFD vs Nm3/h, API gravity, GOR).

NOTE. Pressure conversions are gauge-to-gauge unless explicitly marked absolute (psia, kPa-a). Standard reference for gas flow: 15C and 101.325 kPa (ISO 13443). MMSCFD uses 60F and 14.696 psia (API standard). All conversions for preliminary sizing – verify with your project basis.
