Q & A: What is specific gravity? | Department of Physics ...

Oct 22, 2007 · Water has a specific gravity of 1.000 (near 4°C). If a liquid is more dense than water, then its specific gravity is greater than 1. If it is less dense than water, then the specific gravity is less than 1. To calculate the specific gravity of a liquid, you have to know its density.

Urine specific gravity - Wikipedia

The body excretes some of these waste molecules via urination, and the role of the kidney is to concentrate the urine, such that waste molecules can be excreted with minimal loss of water and nutrients. The concentration of the excreted molecules determines the urine's specific gravity. In adult humans, normal specific gravity values range from ...
