Frequently asked questions
What units does this pressure converter support?
It supports 15 units: Pascal (Pa), Kilopascal (kPa), Megapascal (MPa), Bar (bar), Millibar (mbar), Atmosphere (standard) (atm), Pound per Square Inch (psi) (psi), Kip per Square Inch (ksi) (ksi), Pound per Square Foot (psf), Torr (mmHg) (Torr), Inch of Mercury (0°C) (inHg), Inch of Water (4°C) (inH₂O), Kilogram-force per Square Centimeter (kgf/cm²), Barye (Ba), Micron of Mercury (µmHg).
What is the base unit of pressure?
The SI reference unit is the pascal (Pa). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
