How to Convert Newton per Cubic Metre to Tonne-force per Cubic Metre
- 1 N/m³ = 0.0001019716213 tf/m³
- 1 tf/m³ = 9806.65 N/m³
- Example: convert 15 N/m³ to tf/m³: 15 N/m³ = 15 × 0.0001019716213 tf/m³ = 0.001529574319 tf/m³
Formula
tf/m³ = N/m³ × 0.0001019716212978
or tf/m³ = N/m³ ÷ 9806.65
Derivation from SI units:
- Specific (unit) weight γ = ρ g, in N/m³.
- 1 tf/m³ = 1000 kgf/m³ = 9806.65 N/m³.
Both units are defined exactly, so the factor is exact. Newton per Cubic Metre definition: newton per cubic metre; Tonne-force per Cubic Metre definition: tonne-force per cubic metre.
Worked examples
- A reading of 15000 N/m³ converts to 1.529574319 tf/m³.
15000 N/m³ × 0.0001019716213 = 1.529574319 tf/m³ - A value of 24000 N/m³ is 2.447318911 tf/m³.
24000 N/m³ × 0.0001019716213 = 2.447318911 tf/m³

Where it's used
Newtons per Cubic Metre are used for hydrostatic pressure p = γh, while tonnes-force per cubic metre appear in older Indian soil-mechanics texts. Both measure specific weight (unit weight) γ = ρg, so the conversion is a fixed factor.
