Pressure unit relationships
1 MPa = 1 N/mm² = 10 bar = 145.038 psi
1 bar = 100 kPa = 14.504 psi · 1 kgf/cm² = 0.98067 bar
Hydraulic systems are specified in bar or MPa (psi in North America); material strength and stress use MPa = N/mm² (ksi in the US). Gas pressures for laser cutting are given in bar.

Frequently asked questions
How many psi is 1 bar?
1 bar = 14.5038 psi. 1 psi = 0.0689476 bar.
How do I convert MPa to bar?
Multiply by 10: 21 MPa = 210 bar; 31.5 MPa = 315 bar.
Is N/mm² the same as MPa?
Yes. 1 N/mm² = 1 MPa exactly. Tensile strengths such as 450 N/mm² are 450 MPa (65.3 ksi).
What is kgf/cm²?
An older engineering unit still found on gauges: 1 kgf/cm² = 0.980665 bar = 14.223 psi.
