Question

Specific gravity uses what as the constant 1?

Answer 1

Density of water at 4 degree celsius is taken as constant 1.This is because density of water at 4 degree celsius is maximum.And at this temperature 1cc of water weighs 1 gm.

Answer 2

Since water's density is 1000 kg/m3 in SI units, the relative density of a material is approximately the density of the material measured in kg / m3 divided by 1000 (the density of water). There are no units of measurement.



Water's density can also be measured as nearly one gram per cubic centimetre (at maximum density) in metric units. The relative density therefore has nearly the same value as density of the material expressed in grams per cubic centimetre, but without any units of measurement.Relative density or specific gravity are often ambiguous terms. This quantity is often stated for a certain temperature. Sometimes when this is done, it is a comparison of the density of the commodity being measured at that temperature, with the density of water at the same temperature. But they are also often compared to water at a different temperature.

Answer 3

The weight of one milimeter of pure water H2O at one atmosphere and 72 degreesF. This is called standard tempature and pressure. This weight is one gram. Thus you have g/c.c.
