Tyre Pressure Conversion Help

Higher precision tire pressure conversion

I’m looking to convert tire pressures more precisely, do you have a larger conversion table which more digits or can you suggest a conversion tool which allows more digits in the readings?

To convert tyre pressure readings to a higher precision use this pressure unit converter.

American vs Imperial psi, kPa and bar

I’m using a tyre pressure gauge which was purchased in America, it is scaled in a choice of units: kPa, bar and psi. Is there any difference between the America and Imperial conversion?

The pressure unit bar is a European metric unit which has the same value in every country. Kilopascals (kPa) are derived form the SI unit for pressure which is the pascal (Pa), which is also commonly used in Europe. Pounds per square inch (psi or pfsi) are American and British Imperial units and the value is the same in both measurement systems.

bar: Metric, 100,000 Pa
kPa: SI, Metric, 1,000 Pa
psi: American, British Imperial, 6,894.76 Pa

220 car tyre pressure meaning

Inside the car door, the tyre pressure front and back is listed as 220. what pressure would this convert to in the UK?

It means 220 kPa (kilopascals) = 2.2 bar = 31.9 psi (pounds per square inch)
