About the Density Converter
Density is mass per unit volume and is a key intrinsic property used to identify materials and understand buoyancy (Archimedes' principle). Pure water at 4 °C has a density of exactly 1,000 kg/m³ (1 g/cm³), which serves as a reference point for the concept of specific gravity. Density varies with temperature and pressure, especially in gases.
Quick facts
- ›Osmium is the densest naturally occurring element at 22,590 kg/m³
- ›The density of air at sea level is approximately 1.225 kg/m³
- ›Gold (19,320 kg/m³) is nearly 20× denser than water
- ›Ice is less dense than liquid water (917 vs 1,000 kg/m³) — which is why ice floats
