Result

Density
2,700 kg/m³
Mass (m)
2.7 kg
Volume (V)
0.001 m³
In g/cm³
2.7 g/cm³
Floats in water?
No (denser than water)
How it was calculated
  1. ρ = m ÷ V
  2. ρ = 2,700 kg/m³
Water is about 1,000 kg/m³ (1 g/cm³). 1 litre = 0.001 m³.

How to use the Density Calculator

  1. Pick what to solve for.
  2. Enter the other two values in kg and m³.
  3. Read the result in kg/m³ and g/cm³.

What does this tool do?

Density is mass per unit volume. Aluminium is about 2,700 kg/m³, water 1,000 kg/m³ and oak roughly 750 kg/m³ — which is why oak floats and aluminium sinks.

1 g/cm³ equals 1,000 kg/m³, and 1 litre is 0.001 m³.

Why use it?

  • Solve for any variable.
  • Two common units.
  • Float-or-sink check.

The formula

ρ = m ÷ V
