Density

DENSITY is a measure that compares a substance's MASS to the VOLUME it occupies.

The DENSITY of a material depends on how closely its particles are packed.

A DENSE material means the particles are close together.

If the material is compressed, the particles are forced closer, increasing the DENSITY.

The formula to calculate DENSITY is:

where:

• Mass is measured in Kilograms (kg).
• Volume is measured in Cubic metres (m³).
• Density is measured in Kilograms per cubic meter (kg/m³).

Units of Density

• You might also encounter DENSITY given in grams per cubic centimeter (g/cm³).
