About this tool
Convert density between eight units: kilogram per cubic meter (kg/m³), gram per cubic centimeter (g/cm³), pound per cubic foot (lb/ft³), pound per cubic inch (lb/in³), pound per US gallon (lb/gal), pound per UK gallon (lb/gal UK), ounce per cubic foot (oz/ft³) and slug per cubic foot (slug/ft³). The menus show full names with symbols, and the result is labeled with the symbol. Conversions pass through kg/m³. Water is about 1,000 kg/m³ or 1 g/cm³, which gives a handy check. Density depends on temperature, and the converter does not account for it. Results show up to 8 decimals.
How to use it

Common problems
- US and UK gallons give different results
- The two pound-per-gallon units differ because the gallons differ in size (3.785 vs 4.546 liters).
- The result of a real material seems off
- Density changes with temperature and purity. This tool only changes units, it does not correct for conditions.
