Perguntas frequentes

What is 3 bar in PSI?

3 bar = 43.5 PSI. A quick rule: multiply bar by 14.5.

Why do weather reports use millibars?

Millibar is a convenient unit for atmospheric pressure. Standard sea-level pressure is about 1,013 millibars = 1.013 bar = 14.7 PSI.

Is pressure the same as force?

No. Pressure = Force / Area. PSI means pounds of force per square inch. Bar is a metric absolute pressure unit (0 bar is a vacuum).
