Density Calculator
Find density from mass and volume.
Density tells you how much mass is packed into a given volume.
The math behind it
density = mass ÷ volume. Water is 1,000 kg/m³ (1 g/cm³). Denser-than-water materials sink.
Worked example
2 kg in 0.001 m³ → 2,000 kg/m³ (2 g/cm³).
FAQ
Why do things float?
Objects less dense than the fluid they're in float; denser ones sink.
