Convert Kilograms-force per Cubic Metre to tf/m³
1 kilogram-force per cubic metre (kgf/m³) = 0.001 tonnes-force per cubic metre (tf/m³). 1 tf/m³ = 1000 kgf/m³. Example: 15 kgf/m³ = 15 × 0.001 = 0.015 tf/m³.

How to Convert Kilogram-force per Cubic Metre to Tonne-force per Cubic Metre
- 1 kgf/m³ = 0.001 tf/m³
- 1 tf/m³ = 1000 kgf/m³
- Example: convert 15 kgf/m³ to tf/m³: 15 kgf/m³ = 15 × 0.001 tf/m³ = 0.015 tf/m³
Formula
tf/m³ = kgf/m³ ÷ 1000
Derivation from SI units:
- 1 kgf/m³ = 9.80665 N/m³.
- 1 tf/m³ = 1000 kgf/m³ = 9806.65 N/m³.
- 1 kgf/m³ = 9.80665 N/m³ ÷ 9806.65 N/m³ per tf/m³ = 0.001 tf/m³
Both units are defined exactly, so the factor is exact. Kilogram-force per Cubic Metre definition: kilogram-force per cubic metre; Tonne-force per Cubic Metre definition: tonne-force per cubic metre.
Worked examples
- A reading of 1800 kgf/m³ converts to 1.8 tf/m³.
1800 kgf/m³ × 0.001 = 1.8 tf/m³ - A value of 2400 kgf/m³ is 2.4 tf/m³.
2400 kgf/m³ × 0.001 = 2.4 tf/m³

Frequently asked questions
How many tonnes-force per cubic metre are in 1 kilogram-force per cubic metre?
1 kgf/m³ = 0.001 tf/m³.
How do I convert kilograms-force per cubic metre to tonnes-force per cubic metre?
