How to calculate
Convert PSI, bar and kilopascals without changing the physical pressure.
kPa = PSI × 6.894757293168361; 1 bar = 100 kPa.
Worked example
Pressure: 32; Input unit: 6.894757293168361.
Pressure: 32 PSI; Pressure: 2.21 bar; Pressure: 220.63 kPa.
Assumptions and limits
Convert PSI, bar and kilopascals without changing the physical pressure. Gauge readings stay gauge readings; this does not convert gauge to absolute pressure or recommend a tire inflation pressure. Follow the vehicle placard.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.

Frequently asked questions
Does converting PSI to bar change gauge pressure into absolute pressure?
No. Unit conversion preserves the pressure reference. A gauge reading remains gauge pressure; adding atmospheric pressure to obtain absolute pressure is a separate step.
