›How is density calculated?

Density is mass divided by volume. This converter handles the complex ratios between different mass and volume units automatically.

›Which units are supported?

The tool supports metric units like `kg/m³` and `g/cm³`, alongside imperial units like `lb/ft³`, `lb/in³`, and density relative to US or UK gallons.

›What is the density of water?

Pure water has a density of approximately `1000 kg/m³` or `1 g/cm³` at standard temperature and pressure.

›Are the results precise?

Yes. We use double-precision floating-point arithmetic to ensure accuracy remains high across multiple unit conversions.
