What this converter covers

Convert pressure values between pascals, kilopascals, megapascals, bar, psi, standard atmospheres, and torr.

Worked example

1 Atmosphere (atm) = 14.69594878 PSI

Important unit notes

•A unit conversion does not change whether a reading is gauge pressure or absolute pressure; that depends on the measurement reference.
•The standard atmosphere is defined as 101,325 Pa.

Conversion factors are maintained against documented standards and definitions. Some displayed decimals are rounded for readability.How accuracy is handled·Sources
