Megapascals to pounds per square inch
Type a value in MPa to get it in psi instantly.
That's 8.3× as much pressure as a fire hose, while a scuba tank is 2× higher. Spread over a fingertip, that is like resting 102 kg on it.
What it means
How much pressure is that?
Tyre and tank figures are gauge pressure, measured above the surrounding air. Weather and altitude figures are absolute.
The math
How to convert MPa to psi
To convert megapascals to pounds per square inch, multiply by 145.038.
Example: 10 MPa × 145.038 = 1,450.38 psi.
In the other direction, 1 psi = 0.00689476 MPa.

About these units
Megapascals (MPa)
A megapascal is a million pascals, or 10 bar. Material strength and hydraulic systems are rated in megapascals.
Pounds per square inch (psi)
One psi is one pound of force on one square inch, about 6,895 pascals. US tyre gauges, compressors and plumbing all read in psi.
