MPA Converter
Convert megapascals to bar, psi, atm, torr, kPa, and other pressure units with instant bidirectional results.
What Is the MPa Pressure Unit Converter?
The MPa Converter converts megapascals (MPa) to bar, psi, atm, Torr, and kPa. MPa is the SI unit for high pressure used in hydraulics, structural engineering, and materials science. Enter a value in MPa or in the selected output unit for instant bidirectional conversion.
Conversion Formulas
From 1 MPa, the standard conversion factors are:
- $$\text{bar} = \text{MPa} \times 10$$
- $$\text{psi} = \text{MPa} \times 145.038$$
- $$\text{atm} = \text{MPa} \times 9.86923$$
- $$\text{Torr} = \text{MPa} \times 7500.62$$
- $$\text{kPa} = \text{MPa} \times 1000$$
One megapascal equals one million pascals ($1\ \text{MPa} = 1{,}000{,}000\ \text{Pa}$). It is commonly used for concrete strength, steel yield stress, and hydraulic system ratings.

Frequently Asked Questions
How many bar is 1 MPa?
1 MPa equals 10 bar. Bar and MPa are both metric pressure units, with 1 bar defined as 100,000 pascals and 1 MPa as 1,000,000 pascals.
How do I convert MPa to psi?
Multiply the MPa value by 145.038. For example, 2 MPa equals about 290.076 psi. Use our MPa to PSI Converter for dedicated MPa and psi conversion.
What is MPa used for?
MPa is used for concrete compressive strength (e.g., 30 MPa concrete), steel yield strength, hydraulic pressures, and geotechnical engineering. It is the standard SI unit for high pressure measurements.
How many kPa are in 1 MPa?
1 MPa equals 1000 kPa. Both are SI units where kilo means one thousand and mega means one million pascals.
How do I convert MPa to atm?
Multiply MPa by 9.86923. For example, 0.101325 MPa equals approximately 1 standard atmosphere at sea level.
Is MPa the same as N/mm²?
Yes. One newton per square millimeter equals one megapascal. Both represent $1{,}000{,}000\ \text{N/m}^2$, which is why MPa is common in structural engineering.
