How the Density Unit Converter Works
The Density Unit Converter calculates density from mass and volume in kg/L, then the table converts kg/L into 10 other density units.
Enter mass and volume
Type a mass in kg and a volume in L to get kg/L, or type 1 kg over the volume of 1 kg.
Read kg/L
The result box shows density in kg/L, the same number as g/cm³ and g/mL.
Pick the target unit
Find the target unit in the conversion table.
Multiply by the factor
Multiply the kg/L value by the factor, such as 1,000 for kg/m³ or 8.3454 for lb/US gal.
Density Unit Converter Formula
The density unit identity is 1 kg/L = 1 g/cm³ = 1 g/mL = 1,000 kg/m³ = 8.3454 lb/US gal = 62.428 lb/ft³.
- kg/L
- Kilograms per liter
- kg/m³
- Kilograms per cubic meter, the SI unit
- lb/gal
- Pounds per gallon, used in US coatings and fuels
Worked Examples
- Paint at 11.2 lb/US gal: 11.2 ÷ 8.3454 = 1.3421 kg/L.
- Steel at 7,850 kg/m³: 7,850 ÷ 1,000 = 7.850 kg/L = 490.1 lb/ft³.
- Diesel at 0.832 kg/L: 0.832 × 8.3454 = 6.943 lb/US gal.
Density Unit Converter Conversion Table
1 kilogram per liter equals 1,000 kilograms per cubic meter. The table converts 1 kg/L into 11 density units and shows the factor back to kg/L.
| Unit | Symbol | Equal to 1 kg/L | To Convert into kg/L |
|---|---|---|---|
| Grams per cubic centimeter | g/cm³ | 1 | × 1 |
| Grams per milliliter | g/mL | 1 | × 1 |
| Kilograms per cubic meter | kg/m³ | 1,000 | ÷ 1,000 |
| Grams per liter | g/L | 1,000 | ÷ 1,000 |
| Tonnes per cubic meter | t/m³ | 1 | × 1 |
| Pounds per US gallon | lb/gal | 8.3454 | ÷ 8.3454 |
| Pounds per imperial gallon | lb/imp gal | 10.0224 | ÷ 10.0224 |
| Pounds per cubic foot | lb/ft³ | 62.428 | ÷ 62.428 |
| Pounds per cubic inch | lb/in³ | 0.036127 | ÷ 0.036127 |
| Ounces per cubic inch | oz/in³ | 0.578037 | ÷ 0.578037 |
| Short tons per cubic yard | ton/yd³ | 0.842778 | ÷ 0.842778 |
What is a Density Unit Converter?
A Density Unit Converter is a tool that expresses one density value in metric, SI, US customary and imperial units.
Density units differ by region and trade. European data sheets use kg/m³ or g/cm³, US paint and fuel sheets use lb/gal, and US construction uses lb/ft³.
The kilogram per liter sits at the center of the metric family. 1 kg/L, 1 g/cm³, 1 g/mL and 1 t/m³ share the same number, so metric conversions need no math.
What are the Uses of a Density Unit Converter?
There are 4 main uses of a Density Unit Converter.
Data sheet translation
Engineers convert US lb/gal values into kg/L for metric projects.
Software input
Designers convert densities into the unit a simulation or ERP system expects.
Material takeoffs
Estimators convert lb/ft³ aggregate densities into t/m³.
Homework checks
Students check unit conversions in physics and chemistry problems.
