Calculator for converting between pressure units
For pressure, the SI system’s basic unit is the Pascal (Pa), which is 1 N/m² (Newton per square meter). A newton is equal to the force that would give a mass of one kilogram an acceleration of one metre per second per second (1 kg.m.s^{−2}), and is equivalent to 100,000 dynes. The calculator below can convert between the major pressure units, pascal, kilopascal, bar, millibar, pounds per square inch (psi) and standard atmosphere used in practice. The standard atmosphere is a unit of pressure defined as 101325 Pa (1.01325 bar). It is approximately equal to Earth's atmospheric pressure at sea level.
