Relative Density:
The relative density of a substance is the ratio of its density to that of water.
Relative density of a substance
In other words, we can say that,
Relative density of a substace
Since, the relative density is a ratio of similar quantities, so it has no unit.
The relative density of a substance expresses the heaviness (or density) of the substance in comparison to water. By saying that relative density of iron is 8.7, we mean that iron is 8.7 times heavy as an equal volume of water.
Density of water is
The relative density of a substance is found accurately by using Archimedes principle.
