Common pressure units
The pascal (Pa) is the SI unit of pressure. Kilopascals and megapascals scale it by powers of 1,000. Bar and millibar are commonly used for weather and engineering; PSI is used in many tire pressure readings. One standard atmosphere is exactly 101,325 Pa.
Pressure conversion examples
- 1 bar = 100,000 pascals.
- 1 kPa = 1,000 pascals.
- 1 standard atmosphere = 101,325 pascals.
- 1 bar ≈ 14.5038 PSI.
