⚖️ Density Converter
Convert density units, kilograms per cubic metre, grams per cubic centimetre, g/mL, kg/L, pounds per cubic foot and per cubic inch. Water is 1 g/cm³ = 1000 kg/m³.
1 kg/m³ = 0.001 g/cm³
1 kilograms per cubic metre = 0.001 grams per cubic centimetre
1 × 0.001 = 0.001
1 kg/m³ equals 0.001 g/cm³, so multiplying by 0.001 converts the value. The result describes the exact same quantity, only the measuring stick changes.

All density units
| Unit | Symbol | Definition |
|---|---|---|
| Kilogram per cubic metre | kg/m³ | The SI unit of density, mass in kilograms per cubic metre. Water is 1,000 kg/m³; air at sea level about 1.225 kg/m³. |
| Gram per cubic centimetre | g/cm³ | One gram per cubic centimetre equals 1,000 kg/m³. Water is 1 g/cm³ by definition, which makes this a convenient reference unit. |
| Gram per millilitre | g/mL | Numerically identical to g/cm³ (1 mL = 1 cm³), so 1 g/mL = 1,000 kg/m³. Common for liquids in the lab and kitchen. |
| Kilogram per litre | kg/L | One kilogram per litre is 1,000 kg/m³, the same as g/cm³. Water is 1 kg/L. |
| Gram per litre | g/L | One gram per litre equals 1 kg/m³. Used for dilute solutions and gas densities. |
| Pound per cubic foot | lb/ft³ | The US density unit, about 16.018 kg/m³. Water is about 62.4 lb/ft³; building materials and soils are often specified this way. |
| Pound per cubic inch | lb/in³ | About 27,680 kg/m³, a large unit used for metals. Steel is roughly 0.284 lb/in³. |
