Density, Specific Gravity

Definition:
Density and specific gravity have very similar, but not quite identical definitions.

Density is the mass of material per unit volume.

Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 ^{o}C. Because specific gravity is a ratio, it is a unitless quantity. For example, the specific gravity of water at 4^{o}C is 1.0 while its density is 1.0 gcm^{-3}.

To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. All results shown will be equivalent values. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). Values of 10 000 or greater will be displayed in the e-format e.g. 2.3456e7 which equals 2.3456 x 10^{7} or 23 456 000. Values lower than 0.001 will be displayed in the e-format e.g. 2.3456e-5 which equals 2.3456 x 10^{-5} or 0.000 023456. The calculators require that your browser has java script enabled.
