MPa – Megapascal Pressure Unit

The megapascal is a x1000000 multiple of the pascal unit which is the SI unit for pressure. 1 megapascal equals 1,000,000 pascals.

Primarily used for higher range pressure measurement due to its larger value (e.g. 1 MPa = 10 bar), the MPa is mainly used to describe the pressure ranges and ratings of hydraulic systems. Despite the convenience of using megapascal pressure units to limit the number of digits used on dial gauges and readouts, the bar and the psi pressure unit are still used more commonly used for describing hydraulic pressures.

A pressure value in megapascals can be converted into its equivalent value in another pressure unit by multiplying it by one of the factors in the table below.

To find the conversion factor to convert to megapascals please click on the appropriate unit below or use our unit converter for multiple calculations if you prefer.

MPa to N/mm²

What is 1 MPa equal to in N/mm²?

1 megapascal is exactly equal to 1 N/mm².

1 MPa = 1,000,000 Pa

If 1 Pa = 1 N/m² = 1 N / (1,000 mm x 1,000 mm) = 1/1,000,000 N/mm2

Then 1 MPa = 1,000,000 Pa = 1,000,000 x 1/1,000,000 N/mm2 = 1 N/mm²

MPa to kN/mm²

How is 1MPa  converted into 1kN/mm²?

1 MPa (megapascal) is exactly equal to 1 N/mm2 (Newton per square millimetre)

1 kN/mm² = 1000 N/mm²

Therefore 1 MPa = 1 kN/mm²/1000 = 0.001 kN/mm²
