Did you know?
The pascal (Pa) is the SI unit of pressure. One pascal is equal to one newton per square metre. Because 1 Pa is small, kPa, MPa, or GPa are commonly used in engineering.
In meteorology, hectopascal (hPa) or millibar (mbar) are used. 1 hPa = 1 mbar = 100 Pa. Standard atmosphere (1 atm) is about 1013.25 hPa.
Pound-force per square inch (psi) is an imperial unit widely used for tire pressure and hydraulic systems. 1 psi ≈ 6.895 kPa.
