How to convert Bar to Pascals
1 bar equals 100,000 Pa. Use the converter above for any value, or read the table for common conversions.
Pa = bar × 100000 · bar = Pa × 0.00001Multiply a bar figure by 100,000 to get pascals, or divide it by 1e-5 to go the other way.
Worked examples
- 1 bar= 100,000 Pa
- 2 bar= 200,000 Pa
- 5 bar= 500,000 Pa
- 10 bar= 1,000,000 Pa
- 50 bar= 5,000,000 Pa
What these units are
Bar (bar). One bar is exactly 100,000 pascals, slightly less than one atmosphere. It is used for tyre pressure, industrial gases and weather charts.
Pascals (Pa). The pascal is the SI unit of pressure: one newton per square meter. It is used in science and engineering, usually as kilopascals or megapascals.
Bar, atmosphere and psi are exact definitions. Gauges and weather stations round heavily, so treat the last digit as indicative rather than precise.
Checking a bar to pascals conversion
Pressure units are all defined against the pascal, so the conversion is a multiplication by a fixed number. What makes this dimension awkward is that the numbers sit within tens of per cent of each other, so a small slip looks plausible.
Three of the units are close together on purpose: one bar is 100,000 pascals, one atmosphere is 101,325, and weather reports use millibars and hectopascals, which are the same size. A reading that looks like a unit error is often a genuine difference between gauge pressure and absolute pressure instead.
Checking a pressure conversion means converting through pascals and comparing with a known reference, such as the fact that a bar and an atmosphere differ by about 1.3%. The error to watch for is quoting a pressure without saying whether it is measured above atmospheric pressure or from a vacuum.
