How many pascals are in 1 psi?

One psi (pound per square inch) equals exactly 6,894.757293168 pascals. To convert psi to Pa, multiply by 6,894.757; to convert Pa to psi, divide by 6,894.757.

What is the difference between Pa, kPa, and MPa?

They are all metric pressure units with different scales. 1 kPa = 1,000 Pa; 1 MPa = 1,000,000 Pa. kPa is common for tire pressure and weather data, while MPa is used in material strength and high-pressure systems.

How do I convert kPa to psi?

Divide the kilopascal value by 6.894757. For example, 100 kPa ÷ 6.894757 ≈ 14.504 psi. This tool does that calculation for you automatically when you select kPa as the input unit.

Is psi the same as pound-force per square inch?

Yes. PSI stands for "pounds per square inch" and specifically means pound-force (lbf) per square inch — not pound-mass. It is a gauge or absolute pressure unit used widely in the United States and the UK.

What is standard atmospheric pressure in psi and Pa?

Standard atmospheric pressure (1 atm) is 101,325 Pa or 101.325 kPa, which equals approximately 14.696 psi.

Summary

This tool converts pressure values from pascals (Pa), kilopascals (kPa), or megapascals (MPa) into pounds per square inch (psi). One psi equals exactly 6,894.757293168 pascals — the conversion factor defined by the international standard. Use it for engineering specs, tire pressure data, hydraulic system ratings, or any application that mixes metric and imperial pressure units.
