Instant, two-way conversion across common engineering units.
1 MPa = 145.03774 psi(Megapascal → Pounds per square inch)
To convert megapascals to pounds per square inch, multiply the value by 145.03774. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.
The megapascal (MPa) equals one million pascals, or one newton per square millimeter.
Pounds per square inch (psi) is the pressure unit of US customary engineering.
1 MPa equals 145.03774 psi.
Multiply the value by 145.03774. For example, 10 MPa equals 1,450.3774 psi.
1 psi equals 0.0068947573 MPa. The converter above works in both directions, so you can type into either field.
One kilopascal equals one kilonewton per square meter, which is why imposed floor loads and wind pressures are stated in kPa or kN/m².
One megapascal equals one newton per square millimeter, which matches the millimeter cross-sections used in structural design, so C30/37 or S355 read directly as stress limits.
