1 MPa = 145.038 PSI · 1 MPa = 10 bar

How to convert PSI to megapascals

To convert PSI to megapascals, divide by 145.038. For example, 1000 PSI ÷ 145.038 = 6.895 MPa. Going the other way, multiply megapascals by 145.038 to get PSI.

To convert PSI to bar, divide by 14.5038. So 1000 PSI ÷ 14.5038 = 68.948 bar.

1 MPa = 145.038 PSI = 10 bar = 1,000,000 Pa. PSI is used in the US for everyday pressure measurements while MPa is used for high pressure industrial applications and material strength ratings.

Frequently asked questions

How many MPa is 1 PSI?
1 PSI = 0.00689476 MPa = 0.0689476 bar = 6894.76 Pa.
How many PSI is 1 MPa?
1 MPa = 145.038 PSI = 10 bar = 9.869 atm = 1,000,000 Pa.
How many MPa is 3000 PSI?
3000 PSI = 20.684 MPa = 206.843 bar. Calculation: 3000 ÷ 145.038 = 20.684 MPa.
How many PSI is 10 MPa?
10 MPa = 1450.38 PSI = 100 bar. Calculation: 10 × 145.038 = 1450.38 PSI.
What is MPa used for?
Megapascals are used for material tensile strength, hydraulic systems, concrete compressive strength, and high pressure industrial applications. Steel tensile strength is typically 400-700 MPa.
