psig to kpa - The Ultimate Conversion Guide

What is psig?

Psig stands for pounds per square inch gauge. It is a unit of pressure that is commonly used in the United States. Psig is measured relative to atmospheric pressure, which is the pressure exerted by the weight of the air around us.

What is kpa?

Kpa stands for kilopascals. It is a unit of pressure that is part of the International System of Units (SI). Kpa is a measure of absolute pressure, which is the pressure exerted by a fluid or gas without taking into account atmospheric pressure.

Converting psig to kpa

To convert psig to kpa, you need to add 101.325 to the psig value. This is because atmospheric pressure is equal to 101.325 kpa.

For example, to convert 100 psig to kpa, you would do the following:

100 psig + 101.325 = 201.325 kpa
