Specific gravity tables are used to determine the specific gravity, or relative density, of a substance, which is the ratio of the density of that substance to that of a known substance, usually water. Water is known to ... More » Science Physics

The specific gravity table published by the American Petroleum Institute (API) is a tool for determining the relative density of various types of oil. While it has no units of measurement, an oil's rating is expressed as... More » Science Physics Motion & Mechanics

The specific gravity of gold is 19.32. Specific gravity is determined by dividing the weight of the material by the weight of an equal volume of water. Gold also has a melting point of 1950 degrees Fahrenheit and it weig... More »

Specific gravity, also known as relative density, is the ratio of the weight of a substance to the weight of an equal volume of water at a temperature of 4 degrees Celsius. The weight value in the equation can be substit... More » Science Astronomy

The formula for relative density is the quotient of the mass of the substance divided by the mass of the reference substance. The relative density can also be determined by finding the ratio of the weights in place of th... More » Science Physics

Metal density is higher than water density for two reasons: first, the atomic mass of most conventional metals is higher than the molecular mass of water. Second, metal atoms are held more closely together by metallic bo... More » Science Physics

In English units, the density of water is 1.936 slugs per cubic foot. A slug is different from a pound because the slug measures the mass of a unit, but a pound measures the force of the unit in relation to gravity. More » Science Physics
