Kilogram-force per Cubic Metre (kgf/m³)
The kilogram-force per cubic metre is the gravitational unit of unit weight; numerically it equals density in kg/m³, which is why older texts give water as 1000 kgf/m³.
Symbol: kgf/m³ (ASCII: kgf/m3)
Quantity: specific weight (unit weight) γ = ρg
SI relation: 1 kgf/m³ = 9.80665 N/m³ (exact)
Derivation: 1 kgf/m³ = 9.80665 N/m³.
Exact: yes, by definition
Typical uses
- Older Indian and European design texts
- Gravitational-unit problems
