What is difference between density specific gravity? Quora

Density is the amount of matter in a given volume and defined as mass per unit volume; it has the SI unit kg/m or g/cm and is an absolute quantity. Specific gravity is the ratio of a material's density with that of water at 4 C and is therefore a relative quantity with no units. (Density of water varies with its temperature. It attains maximum density of 1 g/cm- at 4C.

The Specific Gravity of a liquid is that liquid's density compared to water. A liquid with a Specific Gravity of 1.030 is 1.03 times the density of water, for instance. In the case of your beer, there are several factors which can contribute to the density of your wort before fermentation and of your beer when it is finished fermenting.
