The density of water (at 4°C) is exactly 1,000 kg/m³.
Most solids are denser than their liquid forms, but ice is an exception, floating in water.
1 g/cm³ is equivalent to 1,000 kg/m³.

Engineering Fundamentals: Density, Mass, and Volume Formulas

Formula

ρ = m / V

Represents how tightly matter is packed.

Formula

m = ρ × V

The fundamental property of a body.

Formula

V = m / ρ

The amount of space a substance occupies.

Material	State	Density (kg/m³)	Density (g/cm³)
Water	Liquid (4°C)	1,000	1.0
Air	Gas (20°C)	1.225	0.0012
Iron	Solid	7,874	7.87
Gold	Solid	19,300	19.3
