What are TYRE pressures measured in?

pounds per square inch
There are three commonly used measurements of pressure in tyres – PSI, BAR and kPa, and depending on your vehicle, you may need to convert from one to another. Your tyre inflation pressure depends on the amount of air that has been pumped into your tyre. It is measured in pounds per square inch (psi), bar or kPa.

Is PSI measure of pressure?

Pressure measurement is all about PSI. That’s because pounds per square inch (PSI) is the most common unit for measuring pressure in the U.S. It’s important to understand what PSI means and how it is used, as pressure measurement is an important part of life in the 21st century.

What does tire pressure mean?

Tire pressure is the atmospheric pressure inside the tire, usually rated in pounds per square inch (psi) or kilopascals (kPa).

What does the G stand for in PSIG?

PSIG, or pounds per square inch, gauge is a unit of pressure relative to the surrounding atmospheric pressure and the “g” in psig means it’s a relative measurement. PSIG is also referred to as gauge pressure hence the name.

What is the difference between PSI and bar pressure?

The key difference between psi and bar is that psi measures pressure as a one-pound force applied on an area of one square inch whereas bar measures pressure as a force applied perpendicularly on a unit area of a surface. Specifically, psi measures pressure or stress, whereas bar only measures pressure.
