Convert Kilonewtons per Cubic Metre to gf/cm³

Formula

gf/cm³ = kN/m³ × 0.1019716212978

or gf/cm³ = kN/m³ ÷ 9.80665

Derivation from SI units:

• 1 kN/m³ = 1000 N/m³.
• 1 gf/cm³ = 9806.65 N/m³ = 1 tf/m³.
• 1 kN/m³ = 1000 N/m³ ÷ 9806.65 N/m³ per gf/cm³ = 0.1019716212978 gf/cm³

Both units are defined exactly, so the factor is exact. Kilonewton per Cubic Metre definition: kilonewton per cubic metre; Gram-force per Cubic Centimetre definition: gram-force per cubic centimetre.

Worked examples

1. A reading of 18 kN/m³ converts to 1.835489183 gf/cm³.
   18 kN/m³ × 0.1019716213 = 1.835489183 gf/cm³
2. A value of 23 kN/m³ is 2.34534729 gf/cm³.
   23 kN/m³ × 0.1019716213 = 2.34534729 gf/cm³

Where it's used

Kilonewtons per Cubic Metre are used for soil unit weight in effective-stress and bearing-capacity problems, while grams-force per cubic centimetre appear in CGS-unit problems and older literature. Both measure specific weight (unit weight) γ = ρg, so the conversion is a fixed factor.
