I need to disagree. The SI unit of density is the kilogram per cubic
metre (kg/m^3). In these units, water has a density of 1,000 kg/m^3,
and iron of 7,870 kg/m^3. Density is frequently expressed in g/cm^3,
however, and expressed in these units, water has a density of 1.0 g/cm^3
and iron 7.87 g/cm^3. One might also express the density in ounces per
cubic inch (which would certainly a give very different numeric value),
or whatever, as long as it's "mass divided by volume".

Best greetings,
