Convert pressure between PSI, pascals, kilopascals, megapascals, bar, atmospheres, mmHg, torr, inches of water, feet of water, and inches of mercury.
Pressure value:
Enter the pressure amount you want to convert.
From unit:
Select the unit your pressure value is currently in, such as PSI, kPa, bar, or atm.
To unit:
Select the unit you want to convert into. The calculator converts through pascals for consistent results.
A pressure unit converter is useful for plumbing, tire pressure, hydraulics, weather, HVAC, compressed air, vacuum readings, water column measurements, science homework, and engineering estimates.
Pressure readings can use many different units depending on the field, equipment, country, or measurement method.
Multiply PSI by 6.89476. For example, 100 PSI equals about 689.48 kPa.
One bar equals about 14.5038 PSI.
One standard atmosphere equals 101.325 kPa.
The pascal is the SI pressure unit. Kilopascals and megapascals are commonly used for larger pressure values.
