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Centimetre is a cgs system (centimetre, gram, second) pressure unit which is now largely obsolete and officially superceded by the SI system of units. 1 Gram per Square Centimeter is 98.0665 pascals.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