Convert Grams per Liter to Grams per Cubic Centimeter

Formula

g/cm³ = g/L ÷ 1000

Derivation from SI units:

• 1 g/L = 10⁻³ kg ÷ 10⁻³ m³ = 1 kg/m³
• 1 g/cm³ = 10⁻³ kg ÷ 10⁻⁶ m³ = 1000 kg/m³
• 1 g/L = 1 kg/m³ ÷ 1000 kg/m³ per g/cm³ = 0.001 g/cm³

Both units are defined exactly, so the factor is exact. Gram per Liter definition: gram per liter; Gram per Cubic Centimeter definition: gram per cubic centimeter.

Worked examples

1. A reading of 1.98 g/L converts to 0.00198 g/cm³.
   1.98 g/L × 0.001 = 0.00198 g/cm³
2. A value of 35 g/L is 0.035 g/cm³.
   35 g/L × 0.001 = 0.035 g/cm³

Where it's used

Grams per Liter are used for gas densities (CO₂ ≈ 1.98 g/L at 0 °C), while grams per cubic centimeter appear in material and mineral densities. Both measure density (mass per unit volume) and mass concentration, so the conversion is a fixed factor.
