1、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。2、,没有单位（无量纲）。

specific gravity n. The ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water at 4°C (39°F) or of a gas to an equal volume of air or hydrogen under prescribed conditions of temperature and pressure. Also calledrelative density. ...
But if we put a stone in water it will sink. Because stone is denser than water. This is happen because every substance has a different density. Specific gravity is very closely related to Density. And it is also known as relative Density. At the industry level, various techniques, like ...
Specific gravity, more formally known as relative density, is a measure of thedensityof a substance in comparison to the density of water. Forsolidsandliquids, specific gravity is generally measured in relation to water at its densest state (at temperatures of 4 Celsius or 39.2 Fahrenheit), and...

Application Programming Interface (API) hydrometers were developed for crude oils and are defined at 60 F. The specific gravity (SG) also was defined at 60F as the density of a fluid at 60F referred to the density of water at 60F. Thus, direct conversion between the API gravity and ...
In relationship to liquids, the term specific gravity is used to describe the weight or density of a liquid compared to an equal volume of fresh water at 4°C (39° F). If the liquid you are comparing will float on this water it has a specific gravity of less than one (1). If ...
The ratio of the weight of the same volume of ink to water at a certain temperature is called the specific gravity of the ink. Regarding the definition of specific gravity, it is often expressed by D (or d) in some references.The symbol d indicates the ratio of the density of the subs...
