Kilogram-force per square centimetre
Encyclopedia
A kilogram-force per square centimeter (kgf/cm2), often just kilogram per square centimeter (kg/cm2), or kilopond per square centimeter is a unit of pressure
using metric units. Its use is now deprecated; it is not a part of the International System of Units
(SI), the modern metric system. Still, kg/cm2 remains active as a measurement of force primarily due to older torque measurement devices still in use.
In SI units, the unit is converted to the SI derived unit pascal
(Pa), which is defined as one newton per square meter (N/m2). A newton is equal to a kg·m/s2, and a kilogram-force
is 9.80665 newtons, meaning that 1 kgf/cm2 equals 98.0665 kilopascals.
In some older publications, kilogram-force per square centimeter is abbreviated ksc instead of kg/cm2.
Pressure
Pressure is the force per unit area applied in a direction perpendicular to the surface of an object. Gauge pressure is the pressure relative to the local atmospheric or ambient pressure.- Definition :...

Pascal (unit)
The pascal is the SI derived unit of pressure, internal pressure, stress, Young's modulus and tensile strength, named after the French mathematician, physicist, inventor, writer, and philosopher Blaise Pascal. It is a measure of force per unit area, defined as one newton per square metre...
