Density Facts
Higher density: Sinks in liquid
Lower density: Floats in liquid
Buoyancy: Based on density difference
Material selection: Density affects weight
How to use the Density
Enter a density value, select the current unit (kg/m³, g/cm³, lb/ft³, etc.), choose your target unit, and get instant conversion. Used in chemistry, materials science, and engineering.
Formula
All densities convert through kg/m³ (base SI unit). value_in_kg_m3 = input × from_factor; result = value_in_kg_m3 ÷ to_factor.
History & interesting facts
Did you know?
Water has a density of 1 g/cm³ (or 1,000 kg/m³), making it a reference standard. Ice floats because it is less dense than liquid water.
Origin & history
Density is mass per unit volume. Archimedes famously used density to expose counterfeit gold, discovering the principle by displacement.

Frequently asked questions
What is density?
Density is the mass of a substance per unit volume. Formula: Density = Mass ÷ Volume. Units are kg/m³ or g/cm³.
Why does ice float on water?
Ice has a lower density (~0.92 g/cm³) than liquid water (1.0 g/cm³), so it floats. This is unusual; most solids sink in their own liquid.
What is the density of aluminum?
Aluminum has a density of 2.70 g/cm³ or 2,700 kg/m³. It is much less dense than iron (7.87 g/cm³).
