About this calculator
Overview
Density is a measure of mass per unit of volume. It describes how compact or concentrated the matter in an object is.
💡
Pro Tips
Density = Mass / Volume.
Density of pure water is 1000 kg/m³ (or 1 g/cm³).
Objects with density less than the fluid they are in will float.

Fun Facts
"Osmium is the densest naturally occurring element on Earth, about twice as dense as lead."
"Saturn is the only planet in our solar system that is less dense than water; it would theoretically float in a giant bathtub."
"Neutron stars are so dense that a teaspoon of their material would weigh about 6 billion tons."
Formula: ρ = m / V
