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 meaning of SPECIFIC WEIGHT is the weight of a substance per unit volume in absolute units equal to the density multiplied by the acceleration of gravity.
Specific Weightis defined asweight per unit volume. Weight is aforce. The SI unit for specific weight is [N/m3]. The imperial unit is [lb/ft3]. Specific Weight (or force per unit volume) can be expressed as γ = ρ ag(4) where γ = specific weight (N/m3], [lb/ft3] ρ = de...
mass. The weight is the gravitational force that pulls any object to Earth. The specific weight corresponds to the weight per unit of the volume and can be calculated from the specific gravity. Knowing the specific weight, you can easily compute the weight of any amount (volume) of a ...
