Pressure Converter
Convert between all common pressure units including Pascal, kilopascal, bar, atmosphere, PSI, torr, and mmHg. Uses internationally standardized conversion factors for precise results.
Pressure conversion is essential in engineering, meteorology, medicine, and automotive applications. Different fields use different pressure units, making conversion a frequent necessity.
Key Conversion Factors
- 1 atmosphere (atm) = 101,325 Pa (exact, by definition)
- 1 bar = 100,000 Pa (exact)
- 1 PSI = 6,894.757 Pa
- 1 torr = 1/760 atm (exact definition)
- 1 mmHg ≈ 1 torr (very close but technically different)
- 1 atm = 14.696 PSI
- 1 bar = 14.504 PSI
Common Applications
- Tire pressure: measured in PSI (US) or bar (Europe)
- Weather: hectopascals (hPa) or millibars
- Blood pressure: mmHg
- Scuba diving: atm or bar
- Industrial: kPa or MPa
