Kilogram-force per Square Centimeter (kgf/cm²)

A unit of pressure equal to one kilogram-force applied over one square centimeter, used in legacy metric systems

The Kilogram-force per Square Centimeter (kgf/cm²) is a unit of pressure with a history connected to the study of fluids, gases, and atmospheric phenomena. Evangelista Torricelli's invention of the barometer in 1643 was a landmark in pressure measurement, and subsequent work by Blaise Pascal established the mathematical foundations. The pascal — the SI unit — was named in Pascal's honor when the SI system was formalized. The Kilogram-force per Square Centimeter reflects either the SI tradition or the practical conventions of specific industries that standardized their measurements independently.

Accurate pressure measurement is critical in engineering, science, commerce, and everyday life. Using the correct unit and applying conversions precisely prevents errors that can be costly or dangerous in professional applications.

Did You Know?

The deepest point in the ocean — the Challenger Deep in the Mariana Trench — has a water pressure of approximately 110 MPa, or about 1,086 times standard atmospheric pressure. The Kilogram-force per Square Centimeter is one of several units used to express pressures across this extraordinary range.
