Bar to PSI
Convert bar to pounds per square inch instantly. Change the amount or check the formula below.
Same pressure in four units
kPa= 500 kPa
psi≈ 72.518869 psi
bar= 5 bar
atm≈ 4.934616 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
Multiply bar by approximately 14.503773773 to get psi.

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.

Methodology: fixed SI definitions and standards-based factors. For safety-critical use, verify the required industry specification. Check definitions, conventions and sources.
