Convert Tonnes-force per Cubic Metre to kgf/m³
1 tonne-force per cubic metre (tf/m³) = 1000 kilograms-force per cubic metre (kgf/m³). 1 kgf/m³ = 0.001 tf/m³. Example: 15 tf/m³ = 15 × 1000 = 15000 kgf/m³.

How to Convert Tonne-force per Cubic Metre to Kilogram-force per Cubic Metre
- 1 tf/m³ = 1000 kgf/m³
- 1 kgf/m³ = 0.001 tf/m³
- Example: convert 15 tf/m³ to kgf/m³: 15 tf/m³ = 15 × 1000 kgf/m³ = 15000 kgf/m³
Formula
kgf/m³ = tf/m³ × 1000
Derivation from SI units:
- 1 tf/m³ = 1000 kgf/m³ = 9806.65 N/m³.
- 1 kgf/m³ = 9.80665 N/m³.
- 1 tf/m³ = 9806.65 N/m³ ÷ 9.80665 N/m³ per kgf/m³ = 1000 kgf/m³
Both units are defined exactly, so the factor is exact. Tonne-force per Cubic Metre definition: tonne-force per cubic metre; Kilogram-force per Cubic Metre definition: kilogram-force per cubic metre.
Worked examples
- A reading of 1.9 tf/m³ converts to 1900 kgf/m³.
1.9 tf/m³ × 1000 = 1900 kgf/m³ - A value of 2.4 tf/m³ is 2400 kgf/m³.
2.4 tf/m³ × 1000 = 2400 kgf/m³

Where it's used
Tonnes-force per Cubic Metre are used for older Indian soil-mechanics texts, while kilograms-force per cubic metre appear in older Indian and European design texts. Both measure specific weight (unit weight) γ = ρg, so the conversion is a fixed factor.
