Convert pascal, kilopascal, bar, psi, atmosphere, torr and mmHg for engineering, weather and technical work.
How to use this converter
What this category measures
Pressure describes force distributed over an area. Pascal is the SI unit, while kilopascal, bar, psi, atmosphere, torr, and mmHg appear in weather, tires, hydraulics, process equipment, laboratories, and medical or vacuum references.
Where these conversions help
Use this converter for tire and compressor specifications, weather data, hydraulic systems, vacuum equipment, engineering drawings, and laboratory notes. Check whether a source means absolute, gauge, or differential pressure before applying a converted number to a real system.
How results are calculated
Pascal is the base unit and the converter applies standard relationships such as 1 bar = 100,000 Pa and 1 atmosphere = 101,325 Pa. The result is a unit conversion only; it does not add or remove atmospheric pressure from a gauge reading.
