How to convert pascals to bars
To convert a measurement in pascals to bars, multiply the value by 0.00001. The conversion factor comes from the relationship between both units and the pascal.
For example, to convert 5 Pa to bars: 5 × 0.00001 = 0.00005 bar.
What is a pascal?
A pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 N/m²). Named after the French mathematician and physicist Blaise Pascal, the unit was adopted by the International System of Units in 1971. It is a small unit, so everyday pressures are usually expressed in kilopascals or bars.
Common uses of pascals include: Scientific and engineering stress calculations; Meteorological reporting (via hectopascals); Material strength and tensile testing; Fluid mechanics and aerodynamics.
What is a bar?
A bar is a metric unit of pressure equal to exactly 100,000 pascals, roughly equal to atmospheric pressure at sea level. Introduced by Norwegian meteorologist Vilhelm Bjerknes, the bar takes its name from the Greek 'baros' (weight). Although not an SI unit, it remains popular in industry, diving, and weather because it is close to one atmosphere.
Common uses of bars include: Scuba diving depth and tank pressure; Industrial hydraulics and pneumatics; European tire and automotive pressure; Weather systems (via millibars).
Pascals to bars worked examples
Here are some common values converted:
1 Pa = 0.00001 bar 5 Pa = 0.00005 bar 10 Pa = 0.0001 bar 50 Pa = 0.0005 bar 100 Pa = 0.001 bar
Frequently asked questions
How many bars are in one pascal?
One pascal (Pa) equals 0.00001 bars (bar). Multiply any value in pascals by 0.00001 to convert to bars.
How do I convert pascals to bars?
Multiply the value in pascals by 0.00001. For example, 5 Pa × 0.00001 = 0.00005 bar.
How do I convert bars to pascals?
Multiply the value in bars by 100,000, or divide by 0.00001. Use the swap button on the converter above to reverse the direction.
Is the pascal to bar conversion exact?
These conversions use standard SI-derived definitions. 1 atm = 101,325 Pa and 1 psi = 6,894.757 Pa exactly by definition.
What is the formula for pascals to bars?
The formula is: bar = Pa × 0.00001. This comes from the definition of both units relative to the pascal.
