## How to Calculate the Specific Gravity of a Substance -

By Steven Holzner . In physics, a substance’s specific gravity is the ratio of that substance’s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m 3, that ratio is easy to find.For example, the density of gold is 19,300 kg/m 3, so its specific gravity

## Relative density - Wikipedia

OverviewBasic calculationTemperature dependenceUsesMeasurementExamplesSee alsoFurther readingRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference. The term "relative density" is often preferred in scientific usage. If a substance's relative density is less than one then it is less dense than the reference; if greater than

## How to Get Weight From Specific Gravity Sciencing

Specific gravity equals the density of the solid or liquid divided by the density of water at a specific temperature. Once you know the density of that solid object or a specific liquid, you can calculate its mass per unit volume, and from that mass, you can get the weight. That's because density (D) is defined as being the ratio of mass (m) to volume (v), or D = m/v. Once you know the mass ...

## How to Find and Determine the Specific Gravity of a Rock

To determine the specific gravity of a mineral, you simply take a sample of ore of known size and put it into a volume of water.Weigh the water that was displaced by the mineral. This will give you the ratio between the mineral and the water. An example is if a mineral that weighs one hundred grams displaces twenty grams of water the specific gravity of the mineral is 5*0 or the mineral weighs ...
