For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier. The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water.

Energy density and the cost, weight, and size of onboard energy storage are important characteristics of fuels for transportation. Fuels that require large, heavy, or expensive storage can reduce the space available to convey people and freight, weigh down a vehicle (making it operate less efficiently), or make it too costly to operate, even after taking account of cheaper fuels.
