Pressure is a fundamental physical quantity that describes the normal force exerted per unit area. In engineering, it is essential to express pressure in units that match the scale of the problem, ranging from pascals (Pa) for small pressures to megapascals (MPa) for high‑pressure systems.
Common pressure units include kilopascals (kPa), pounds per square inch (psi), bars, and atmospheres (atm). Each unit is defined by a fixed relationship to the SI unit pascal, allowing straightforward conversion through multiplication or division by a constant factor.
The conversion can be expressed mathematically as a ratio of the source unit factor to the target unit factor. For example, converting from pascals to atmospheres uses the factor 101 325 Pa per atm.
