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Centimetre is a cgs system (centimetre, gram, second) pressure unit which is now largely obsolete and officially superceded by the SI system of units. 1 Gram per Square Centimeter is 98.0665 pascals.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

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 / (Time x Time)
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
