Specific Gravity, on the other hand, is defined as the weight of a sample, at a given temperature, divided by the weight of the same volume of water, at the same temperature or a different specified temperature. ... Specific Gravity of liquids is most conveniently measured using a Hydrometer.

What is specific gravity and how is it measured?

Measuring or comparing

Specific gravity is the ratio of a material's density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m^-3). It is therefore a relative quantity with no units.

How do you measure specific gravity of a liquid?

Use the equation "m / v = D" where m is mass in grams or kilograms, v is volume in milliliters or liters, and D is density. For example, if you had a sample that was 8 grams and 9 milliliters, your equation would be: "8.00 g / 9.00 mL = 0.89 g/mL." Weigh an empty container first and record its weight.
