What is Pressure Conversion?
Convert between pascal (Pa), bar, psi, atm, mmHg, inHg, and more. Used in meteorology, engineering, medicine, and aviation.
Supported units: Pascal (Pa), Kilopascal (kPa), Hectopascal (hPa), Megapascal (MPa), Standard Atmosphere (atm), Bar (bar), Millibar (mbar), Pound per Square Inch (psi), Millimeter of Mercury (mmHg), Inch of Mercury (inHg), Millimeter of Water (mmH₂O), Torr (Torr).
Common Conversions
- 1 Pascal (Pa) = 0.001 Kilopascal (kPa)
- 1 Pascal (Pa) = 0.01 Hectopascal (hPa)
- 1 Kilopascal (kPa) = 1000 Pascal (Pa)
- 1 Kilopascal (kPa) = 10 Hectopascal (hPa)
- 1 Hectopascal (hPa) = 100 Pascal (Pa)
- 1 Hectopascal (hPa) = 0.1 Kilopascal (kPa)
FAQ
Q: How many Pa in 1 atm?
A: 1 standard atmosphere (atm) = 101,325 Pa.
Q: How to convert bar to psi?
A: Multiply by 14.5038. Example: 2 bar × 14.5038 ≈ 29.0 psi.
Q: What is the standard atmospheric pressure in hPa?
A: 1 atm = 1,013.25 hPa. Meteorologists commonly use hPa (equivalent to mbar) to report air pressure.
