g/cm² - Grams per Square Centimetre Pressure Unit

Grams or Grams Force per Square Centimetre is a cgs system (centimetre, gram, second) pressure unit which is now largely obsolete and officially superceded by SI system of units. 1 Gram per Square Centimeter is 98.0665 Pascals.

The gf/cm2 pressure unit is comparable in value to 1 mbar (hPa) and is used for low pressure measurements of gas burners, and pneumatic valves for example. It is also used as a measure of stress of biological and textile material.

g/cm² Derivation
The calculation below shows how the pressure unit Gram per Square Centimetre (g/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 Gram = 0.001 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 Gram Force = 0.001 kg x 9.80665 m/s² = 0.00980665 N
1 g/cm² Pressure = 0.00980665 N / 0.0001 m² = 98.0665 Pa
