PSI to kPa
Convert pounds per square inch to kilopascals instantly. Change the amount or check the formula below.
Same pressure in four units
kPa≈ 34.473786 kPa
psi= 5 psi
bar≈ 0.344738 bar
atm≈ 0.34023 atm
Gauge vs absolute: these are unit changes only. The reference stays the same; converting a gauge reading to absolute pressure needs a separate measured ambient pressure.
1 bar = 100 kPa. 1 standard atm = 101.325 kPa. Definitions and sources.More actions

Pressure versus force
Pressure describes force over area. PSI, kPa, bar and standard atmosphere are pressure units, not mass or force units. When working with tires or instruments, distinguish gauge pressure from absolute pressure.
A standard atmosphere is 101,325 pascals and one bar is 100,000 pascals by definition. A unit conversion does not determine whether the measurement is gauge or absolute.
