How to convert bar to pascal (pa)
Pressure is force per unit area. Pascals (and kPa, hPa) are SI, while bar and psi are widely used in engineering and scuba. Conversions must respect absolute vs gauge references when comparing values.
This converter calculates Bar to Pascal (Pa) values by using the correct conversion rule for the Pressure category. For linear units, standardized factors are used. For temperature, the calculator applies the proper formula with offsets.

Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Comparing gauge pressure (psig) with absolute pressure (psia/hPa) without converting reference.
- Mixing bar with atm (1 atm = 1.01325 bar).
Unit facts
- Bar: One bar is exactly 100,000 Pa; convenient near-atmospheric unit used in meteorology and diving.
- Pascal (Pa): Pascal (Pa) is the SI unit of pressure: 1 Pa = 1 N/m².
About Bar
Bar
Equals 100,000 Pa (exact). Handy engineering unit near mean sea-level pressure (≈1.01325 bar).
History: Introduced by early 20th-century meteorologists; remains popular in scuba, hydraulics, and weather.
About Pascal (Pa)
Pascal (Pa)
SI unit equal to 1 N/m². Used for stress, tire pressure (kPa), and atmospheric science (hPa).
History: Named after Blaise Pascal; became practical with digital sensors capable of stable low-pressure readings.
