Density Converter
Density Converter: convert between 8 density units, for example 1 g/cm³ = 1000 kg/m³.
| Unit | Value |
|---|---|
| gram per cubic centimeter to kilogram per cubic meter | 1000 kg/m³ |
| gram per cubic centimeter (g/cm³) | 1 g/cm³ |
| gram per cubic centimeter to kilogram per liter | 1 kg/L |
| gram per cubic centimeter to gram per liter | 1000 g/L |
| gram per cubic centimeter to milligram per liter | 1000000 mg/L |
| gram per cubic centimeter to pound per cubic foot | 62.42796058 lb/ft³ |
| gram per cubic centimeter to pound per cubic inch | 0.036127292 lb/in³ |
| gram per cubic centimeter to pound per gallon | 8.345404452 lb/gal |
Convert between kg/m³, g/cm³ (g/mL), kg/L, g/L, mg/L, lb/ft³, lb/in³ and lb/gal. Density links mass and volume: ρ = m / V.
Density, specific gravity and concentration
Specific gravity is density divided by the density of water (about 999.97 kg/m³ at 4 °C), so a value in g/cm³ is very close to specific gravity. mg/L is a mass concentration; in dilute water solutions it is roughly equal to ppm by mass.
Density unit definitions
- kilogram per cubic meter (kg/m³)
- The kilogram per cubic metre (kg/m³) is the SI unit of density. Water near room temperature is about 998 kg/m³ and air at sea level about 1.2 kg/m³.
- gram per cubic centimeter (g/cm³)
- The gram per cubic centimetre (g/cm³, equal to g/mL) is a common laboratory density unit. Water is about 1 g/cm³, which makes the number equal to specific gravity to a good approximation.
- kilogram per liter (kg/L)
- The kilogram per litre (kg/L) equals g/cm³. Fuel and chemical densities are often quoted this way.
- gram per liter (g/L)
- The gram per litre (g/L) is exactly 1 kg/m³. It is also used for concentrations of dissolved substances.
- milligram per liter (mg/L)
- The milligram per litre (mg/L) is a mass concentration, 0.001 kg/m³. In dilute water solutions it is roughly equal to parts per million (ppm) by mass.
- pound per cubic foot (lb/ft³)
- The pound per cubic foot (lb/ft³, pcf) is the US customary density unit, about 16.02 kg/m³. Water is about 62.4 lb/ft³.
- pound per cubic inch (lb/in³)
- The pound per cubic inch (lb/in³) is used for metal and plastic densities in US engineering, about 27 680 kg/m³.
- pound per gallon (lb/gal)
- The pound per US gallon (lb/gal, ppg) is about 119.83 kg/m³. Water weighs about 8.34 lb/gal. Reference: Per US gallon (231 in³).
