# Convert tire pressure without changing the physical reading
Use this tire pressure converter when a gauge, service station or vehicle placard uses a different unit. Enter one reading and get PSI, bar, kPa and kgf/cm² in one view.# How to use the converter
- Enter the pressure shown by the gauge.
- Choose the unit printed beside that reading.
- Select Front, Rear or All axles to keep your note organized.
- Read the equivalent value in the conversion strip.
The converter does not choose your target pressure
Find the recommended cold pressure on the vehicle information placard or in the owner manual. The number moulded on a tire sidewall is a maximum for the tire, not a vehicle-specific recommendation.# Pressure units at a glance

Check the condition of the reading
Pressure changes with temperature. For a reliable comparison, follow the vehicle maker instructions for checking a cold tire and use a trustworthy gauge.
