Gram-force per Cubic Centimetre (gf/cm³)

The gram-force per cubic centimetre is the CGS gravitational unit of unit weight, numerically equal to specific gravity.

Symbol: gf/cm³ (ASCII: gf/cm3)

Quantity: specific weight (unit weight) γ = ρg

SI relation: 1 gf/cm³ = 9806.65 N/m³ (exact)

Derivation: 1 gf/cm³ = 9806.65 N/m³ = 1 tf/m³.

Exact: yes, by definition

Same quantity as tonne-force per cubic metre (tf/m³) : the factor between them is exactly 1.
