Density is mass per unit volume. Materials science quotes kg/m³, chemistry labs use g/cm³ or g/mL for liquids, and US civil specs sometimes use lb/ft³. This converter switches between those units from one input — every value normalizes through kg/m³ for consistent results.
Enter a number, pick From and To, and read the result instantly. All math runs in your browser; nothing is uploaded.
SI uses kg/m³; labs often quote g/cm³ (grams per cubic centimetre). The factor is exactly 1,000 because 1 g/cm³ = 1,000 kg/m³. Cubic centimetre (cc) and cm³ are the same volume unit.
kg/m³ = g/cm³ × 1,000 · g/cm³ = kg/m³ ÷ 1,000
Material examples: water ≈ 1 g/cm³ = 1,000 kg/m³ at 4°C · mercury ≈ 13.6 g/cm³ = 13,600 kg/m³ · gold ≈ 19.3 g/cm³ = 19,300 kg/m³ · aluminium ≈ 2.79 g/cm³ = 2,790 kg/m³.
Divide kg/m³ by 1,000 to get g/cm³. US specs use lb/ft³: multiply kg/m³ by 0.062428 for lb/ft³, or note that 1 lb/ft³ ≈ 16.02 kg/m³. Water at about 1,000 kg/m³ equals roughly 62.4 lb/ft³.
Example: 900 kg/m³ ≈ 56.2 lb/ft³ — typical for some bulk aggregates or light fuels. Select lb/ft³ in the dropdown for imperial ↔ metric density.
For liquids, one millilitre equals one cubic centimetre, so g/mL and g/cm³ are numerically identical. Diesel might show specific gravity (SG) around 0.85 relative to water — multiply SG by 1,000 to get kg/m³ (850 kg/m³ for SG 0.85).
Specific gravity has no units; it is density divided by water density. SG 1.0 means 1 g/cm³ = 1 g/mL = 1,000 kg/m³.
Converting cubic metres to kilograms is not a direct unit swap: mass = density × volume (m = ρ × V). Convert density to kg/m³ here, multiply by volume in m³, or use the Volume Converter for volume units first.
Dynamic viscosity (Pa·s, cP) is different from density — see the Viscosity Converter. This page handles mass per volume only.
Temperature and porosity change real-world values — use datasheet numbers when precision matters, then convert units here.
g/cm³ → kg/m³: 2.79 g/cm³ × 1,000 = 2,790 kg/m³ (aluminium)
kg/m³ → g/cm³: 1,000 kg/m³ ÷ 1,000 = 1 g/cm³ (water)
kg/m³ → lb/ft³: 900 kg/m³ × 0.062428 = 56.2 lb/ft³
Mercury: 13.6 g/cm³ = 13,600 kg/m³
One millilitre equals one cubic centimetre, so liquid densities in g/mL and g/cm³ are numerically identical.
SG has no units — it is ρ ÷ ρ_water. SG 1.0 = 1 g/cm³ = 1,000 kg/m³. Multiply SG by 1,000 for kg/m³.
Converting m³ to kg needs a material density. Convert ρ to kg/m³ here, then multiply by volume in m³.
Multiply g/cm³ by 1,000. For example, 2.79 g/cm³ equals 2,790 kg/m³.
Divide kg/m³ by 1,000. 1,000 kg/m³ equals 1 g/cm³.
Same as g/cm³ — multiply by 1,000.
Multiply kg/m³ by 0.062428. 900 kg/m³ is about 56.2 lb/ft³.
About 1 g/cm³ = 1 g/mL = 1,000 kg/m³ at 4°C.
Multiply SG by 1,000 (relative to water).
Multiply m³ by material density in kg/m³ — not a direct unit conversion.
Yes. cc means cubic centimetre.
