How do I convert pascals to bar?

Divide the pressure in pascals by 100000. For example, 100000 Pa ÷ 100000 = 1 bar.

How many pascals are in one bar?

One bar equals exactly 100000 pascals (100 kPa).

How do I convert bar back to pascals?

Multiply the bar value by 100000. So 2.5 bar × 100000 = 250000 Pa. Typing in the bar field does this automatically.

What is the difference between bar and atmospheres?

One bar is 100000 Pa, while one standard atmosphere is 101325 Pa. So one bar is about 0.987 atm — close to, but not exactly, atmospheric pressure at sea level.

How does bar relate to kPa and hPa?

One bar is 100 kPa or 1000 hPa (hectopascals, the unit used in weather reports). A typical sea-level pressure of about 1013 hPa is roughly 1.013 bar.

Where is the bar unit commonly used?

Bar is widely used for tyre pressures, diving, HVAC and industrial process pressures, because the numbers are conveniently sized — car tyres run around 2 to 2.5 bar.

Pascal to Bar Converter

This free pressure converter changes pascals (Pa) into bar and back again. The pascal is the SI unit of pressure (one newton per square metre), but it is a small unit, so the bar — equal to 100,000 Pa — is often more convenient for everyday and industrial pressures like tyres, pumps and weather systems.

How it works

The conversion uses one exact relationship:

bar      = pascals ÷ 100000
pascals  = bar × 100000

Type a value in either field and the other updates in real time. Because the factor is exact, no rounding error is introduced beyond display formatting.

Example

Convert 250000 Pa to bar:

250000 ÷ 100000 = 2.5 bar

And the reverse, 2.5 bar to pascals:

2.5 × 100000 = 250000 Pa

Pascals (Pa)	Bar (bar)
1000 Pa	0.01 bar
50000 Pa	0.5 bar
100000 Pa	1 bar
250000 Pa	2.5 bar
1000000 Pa	10 bar
