A measure of the total solids content of a product; the ratio of the weight of a given sample in air to the same weight of that sample in water at 77 °F (25 °C), i.e.
An object’s dry weight divided by the weight of water. Used to determine the percentage of fat in a person’s body.
Ratio of the weight of the body to the weight of an equal volume of water.
Measure of the density of the urine compared to that of water.
The concentration of solutes in a urine specimen compared with a standard specimen; may be altered by disease and other factors.
The weight of a substance compared with the weight of an equal volume of water. For solid and liquid materials, water is used as a standard and considered to have a specific gravity of 1.000. For gases, the weight per unit volume is compared with that of dry air at a specified temperature and usually at atmospheric pressure.
The ratio of the density of a given substance to the density of water.
The comparison between the density of a substance and that of water is termed its specific gravity. This measurement, such as in urine, can denote whether the substance holds a significant concentration of dissolved materials (around 1.030) or is nearly as watery as water itself (around 1.010).
