Converting megapascals to bar

To convert megapascals to bar, multiply the value by 10. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.

Megapascal (MPa)

The megapascal (MPa) equals one million pascals, or one newton per square millimeter.

Origin
A decimal multiple of the SI pascal.
Where it is used
Used for concrete and steel strength grades and material stress limits.
Relation to SI
1 MPa = 1,000,000 Pa = 1 N/mm².

Bar (bar)

The bar is a metric pressure unit close to atmospheric pressure at sea level.

Origin
A non-SI unit retained in industry, defined as exactly 100,000 Pa.
Where it is used
Used for pipework, pumps, hydraulics and pressure testing.
Relation to SI
1 bar = 100,000 Pa = 100 kPa exactly.

Frequently asked questions

How many bar are in one megapascal?

1 MPa equals 10 bar.

How do I convert megapascals to bar?

Multiply the value by 10. For example, 10 MPa equals 100 bar.

How do I convert back from bar to megapascals?

1 bar equals 0.1 MPa. The converter above works in both directions, so you can type into either field.

How does pressure relate to structural loading?

One kilopascal equals one kilonewton per square meter, which is why imposed floor loads and wind pressures are stated in kPa or kN/m².

Why are concrete and steel grades given in MPa?

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.

Is this pressure converter free to use?

Yes. Every unit conversion runs in your browser, needs no account and is free for professional use.
