specific weight = weight/volume就是比重，单位是 （N/m^3或者 lb/ft^3）而gravity 指的是地心引力，所以不是用力来算的，而是用密度，所以，specific gravity=density /density of water @4 摄氏度，可翻译为相对密度，，没有单位（无量纲）。

The specific gravity stands for a dimensionless unit that defines the ratio of density of a substance to the density of water. The density of water is 1000 kg/cubic meters at 4 Celsius. In physics, the weight of the substance differs from its mass. The w
is a measure of the amount of matter an object contains while weight is a measure of the force of gravity on the object. In the imperial system, the unit for mass is the slug and the unit for weight is the newton. The pound is also a unit of weight. One pound equals 4.45 newtons...
