How to use the MPa to Bar Converter

Type a value in the Megapascals box. The bar result appears instantly.
Going the other way? Type in the Bar box, or press the ⇄ swap button.
Set the precision with the decimal places menu.
Check the working in the step-by-step box, then press Copy result or click any row in the tables below.

Megapascals to bar formula

bar = MPa × 10

Take the value in megapascals.
Multiply it by 10 (the number of bar in one megapascal).

Example: 30 MPa × 10 = 300 bar.

Reverse formula (bar to megapascals): MPa = bar ÷ 10. Example: 400 bar ÷ 10 = 40 MPa.

The factor is a whole number (10), so this one is easy to do in your head.

About megapascals and bar

Megapascals (MPa). The megapascal (MPa) is one million pascals, about 145 psi. Material strengths (concrete 25–40 MPa, steel 250+ MPa) and hydraulic pressures use MPa.

Bar (bar). The bar is a metric pressure unit equal to 100,000 pascals, very close to atmospheric pressure at sea level (1 atm = 1.01325 bar).

Frequently asked questions

How many bar in 1 megapascal?

One megapascal equals 10 bar.

How do you convert megapascals to bar?

Multiply the number of megapascals by 10. For example, 30 MPa × 10 = 300 bar.

What is 40 megapascals in bar?

40 MPa is 400 bar (c40 concrete).

How much is 250 megapascals in bar?

250 megapascals equals 2,500 bar.

How do I convert bar back to megapascals?

Divide by 10, or press the ⇄ swap button above. For example, 400 bar ÷ 10 = 40 MPa.

Is 1 bar equal to atmospheric pressure?

Almost. 1 bar = 100 kPa, while standard atmospheric pressure is 1.01325 bar (101.325 kPa).
