Converting pressure units

Pressure in the oilfield is measured in psi (pounds per square inch) in North America and in bar or kPa/MPa in metric regions. Frac treating pressures can exceed 10,000 psi, while BOP stacks are rated to 5,000, 10,000 or 15,000 psi.

Key factors: 1 bar = 14.5038 psi, 1 MPa = 145.04 psi, and 1 atm = 14.696 psi. The converter above uses exact definitions for every unit.
