Definition of psig and kg/cm2

psig (Pounds per Square Inch Gauge)

psig is a unit of pressure measured relative to the atmospheric pressure. It represents the pressure above the surrounding atmospheric pressure. For instance, a pressure of 100 psig indicates that the pressure is 100 pounds per square inch greater than the current atmospheric pressure.

kg/cm2 (Kilograms per Square Centimeter)

kg/cm2 is a unit of pressure measured in the metric system. It represents the force exerted by a mass of one kilogram acting on an area of one square centimeter. For example, a pressure of 1 kg/cm2 indicates that a force of one kilogram is acting on an area of one square centimeter.

Conversion Formula

1 psig = 0.070307 kg/cm2

100 psig to kg/cm2
