Pressure Converter
Pressure is force applied over an area
kPa → psi
0.145038 psi
Pressure is force applied over an area. Pascals and kilopascals are SI standards, bar and atmospheres appear in science, and pounds per square inch or inches of mercury are familiar on gauges and weather reports. Convert to match tire specs, hydraulics, or lab instruments.

Common Questions
What is the Pressure converter used for?
Pressure is force applied over an area. Pascals and kilopascals are SI standards, bar and atmospheres appear in science, and pounds per square inch or inches of mercury are familiar on gauges and weather reports. Convert to match tire specs, hydraulics, or lab instruments.
How many PSI are in one atmosphere of pressure?
One standard atmosphere (atm) is defined as exactly 14.696 pounds per square inch (psi), which is equivalent to 101.325 kilopascals (kPa) or 760 mmHg at sea level.
What is the mathematical difference between bar and barg?
The unit 'bar' refers to absolute pressure, which includes the weight of the Earth's atmosphere. The unit 'barg' stands for bar gauge, which sets the baseline zero at local atmospheric pressure. Therefore, bar absolute = barg + 1 atm.
