About pressure units
Common pressure units
Pascal (Pa)
One newton per square meter. The SI unit. Small — most everyday pressures are in kilopascals.
Bar
100,000 Pa. Roughly atmospheric pressure at sea level.
PSI
Pounds per square inch. The everyday US unit for tire pressure.
Atmosphere (atm)
Average sea-level air pressure. 1 atm ≈ 14.7 psi ≈ 1.013 bar.
Frequently asked
What PSI should my car tires be?
Check the sticker inside the driver-side door. Typically 30–35 psi cold for passenger cars.
