Abstract: Before attempting to discuss the methods of determining specific gravity, perhaps specific gravity should be defined. Specific gravity of a gas is the ratio of the weight of a given volume of gas at a definite pressure and temperature to the weight of an equal volume of dry and carbon dioxide free air under the same pressure and temperature conditions. The term density is used frequently in gas measurement and should not be confused with specific gravity. The density of a gas will vary according to the conditions under which it is determined but the specific gravity remains constant when using dry and carbon dioxide free air at unity as a standard. However, specific gravity can be defined as a ratio of the density of a gas to the density of air when both densities are determined under the same conditions of pressure and temperature. Natural gas with a specific gravity of .600 is 60% as heavy as air. A gas such as propane with a specific gravity of 1.522 is approximately 150% as heavy as air.
