The specific gravity of liquids is almost always measured with reference to water at a temperature of 4 ℃ or 39.2 ° F; the specific gravity of gases is almost always measured with reference to air at room temperature of 20 ℃ or 68 ° F. How to measure specific gravity? Specific gravit...
The article focuses on the effectiveness of urine specific gravity test for urine concentrating capacity. The kidneys' response ability to concentrate or dilute urine is measured by urine osmolality which can be measured indirectly by urine specific gravity and directly by osmometry. The urine specific...

the diameters that are perpendicular to each other are measured at least twice, and when the difference between the two measured results is not more than 2 mm, the average value can be taken; if the difference between the two measured diameters is more than 2 mm, the test needs to be re...
The device most often use to determine the specific gravity of a fluid when its value is unknown is called a hydrometer. These come in a number of forms, but the basic construct is a tube weighted at the bottom so that it will sink to a certain point in the test fluid, which...
Specific gravity (SG) is a lot simpler than you and your alien friends expected: It's just the ratio of the density of a given object to the density of waterat a specific temperature.Specific gravity has no units.Its utility lies in the fact that the density of some objects changes with...

Specific gravity is the density of a substance divided by the density of water. Once you know density, you know mass per unit volume, and from that you can determine the weight. In the imperial measurement system, you have to convert the mass in slugs to weight in pounds. ...
First, specific gravity is very closely related to density, and the terms are often used interchangeably. As with a lot of concepts in the world of science, this is generally acceptable, but when considering the effect that small changes in meaning and quantities can have on the physical world...
