Converting bar to pascals

To convert bar to pascals, multiply the value by 100,000. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.

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.

Pascal (Pa)

The pascal (Pa) is the SI derived unit of pressure, equal to one newton per square meter.

Origin
Named after Blaise Pascal and defined directly from SI base units.
Where it is used
Used for wind pressure, duct pressure and stress values in structural analysis.
Relation to SI
1 Pa = 1 N/m², the SI anchor unit for pressure.

Frequently asked questions

How many pascals are in one bar?

1 bar equals 100,000 Pa.

How do I convert bar to pascals?

Multiply the value by 100,000. For example, 10 bar equals 1,000,000 Pa.

How do I convert back from pascals to bar?

1 Pa equals 0.00001 bar. 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.
