Density Facts
- • Density = Mass ÷ Volume (ρ = m/V)
- • Water has a density of 1.0 g/ml at room temperature
- • Objects less dense than water will float
- • Temperature and pressure affect density
- • Specific gravity is density relative to water

How it works
Density tells you how much mass is packed into a given volume. Divide mass by volume to get it. Rearranged, the same relationship finds mass from density and volume, or volume from mass and density.
Density
ρ = m ÷ V (so m = ρ · V and V = m ÷ ρ)
- ρ
- density (e.g. g/cm³ or kg/m³)
- m
- mass
- V
- volume
Worked example
- Mass = 200 g
- Volume = 100 cm³
- ρ = 200 ÷ 100
Density = 2 g/cm³.
Good to know
- Water is ~1 g/cm³, so anything denser than 1 sinks and anything less floats.
- Keep units consistent — g with cm³, or kg with m³ — or convert first.
- Density changes with temperature (things expand when heated), so values are usually quoted at a reference temperature.
