🧱 Density Calculator
Mass, volume and density relationships
About this calculator
Density is how much mass is packed into a given volume, and this calculator solves for any one of the three. Enter any two of mass, volume, and density and it computes the third, converting between grams, kilograms, litres, and cubic metres automatically.
The formula is density equals mass divided by volume. Water is the everyday reference at 1,000 kg per cubic metre (1 g per cubic centimetre) — anything denser sinks, anything less dense floats, which is why ice and oil sit on top of water.
Tip: Watch your units: mixing grams with cubic metres is the most common mistake. Convert everything to kilograms and cubic metres first, or let the calculator handle it.
