**Kilogram or Kilogram Force per Square Centimeter (kg/cm2 or kgf/cm2) is a pressure unit that has been largely superceded by the SI unit system of pascal units. It is the metric equivalent of pounds per square inch (psi). 1 kg/cm2 equals 98,066.5 Pascals.**

Simlarly to psi, kg/cm2 is part of a group of pressure units that relate pressure with weight. This is convenient in applications where a pressure is applied to generate a load such as in material testing. Typically a piston cylinder device is utilised to convert the applied pressure into a force. The force can be easily calculated in kilograms weight by multiplying the kg/cm2 pressure by the area to determine the weight applied in kilogrammes.

The most popular way of writing Kilogrammes per Square Centimeter is as kg/cm2, even though kgf/cm2 describes its meaning more accurately. The conventional way of writing it is misleading to some, since it reads as Mass / Unit Area and leads to confusion since pressure is always defined as Force / Unit Area.

To calculate a kg/cm2 reading into another pressure unit you can multiply it by one of the values in the table below. To convert a value to kgf/cm2 just click on the relevant unit below to obtain the reverse conversion factor.

Alternatively If you have a number of values to convert you can use the pressure converter to save time.

kg/cm² Derivation

The calculation below shows how the pressure unit Kilogram per Square Centimetre (kg/cm²) is derived from SI Units.**Formula**

Pressure = Force / Area

Force = Mass x Acceleration

Acceleration = Distance / (Second x Second)

**SI Units**

Mass: Kilogram (kg)

Length: Metre (m)

Time: Second (s)

Force: Newton (N)

Pressure: Pascal (Pa)

**Input Values**

1 Kilogram = 1 kg

1 Centimetre = 0.01 m

1 Square Centimetre = 0.01 m x 0.01 m = 0.0001 m²

Acceleration = Standard Gravity = 9.80665 m/s²

**Calculation**

1 Kilogram Force = 1 kg x 9.80665 m/s² = 9.80665 N

1 kg/cm² Pressure = 9.80665 N / 0.0001 m² = 98066.5 Pa
