Mass (the unit of mass of S.I. = kilogram)

Attention not to confuse mass and weight.

The mass (kg) is a intrinsic characteristic of the body and is measured in kilogram.

Masse spécifique ou volumique = quotient de la masse d'un corps par son volume.

Specific mass = quotient of the mass of a body by its volume

Weight is a force which depends on terrestrial attraction and it is the equivalent of the mass of a body by the acceleration of gravity (9.80665 at the sea level) and is measured in Newton [ N ].

For example a man of 75 kg (it is its mass, and not its weight contrary to the current expression), has a weight of: 75 * 9.80665 = 735,5 N on the sea level.

Specific Gravity
The density of gas, relative to air, is called specific gravity. The specific gravity of air is defined as 1. Since propane gas has a specific gravity of 1.5, propane-air mixtures have a specific gravity of greater than 1.
