Convert Pascal (Pa) to Bar
Category: Pressure
1 pa = 1E-05 bar
Precision: 6 decimals; very small non-zero results use significant digits.
How to convert pascal (pa) to bar
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.

Conversion formula
Use the following formula:
Bar ≈ Pascal (Pa) × 1E-05
Convert pressure from Pascal (Pa) to Bar using a fixed unit ratio. Round only the final result.
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
- Pascal (Pa): Pascal (Pa) is the SI unit of pressure: 1 Pa = 1 N/m².
- Bar: One bar is exactly 100,000 Pa; convenient near-atmospheric unit used in meteorology and diving.
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.
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.
