Now, I always thought the displaced water of the object, which I
already found, was the same as the volume of the object. Am I
correct? Because then the specific gravity would be equal to the
density, right? If you could e-mail me back ASAP, that would be
great. Thank you. Jennifer Slevin
Hello Jennifer, the difference between density and specific gravity is
Density is measured in units, for example kilogramms per cubic
decimeter, or other units.
Specific gravity is a mere number, applicable to any unit system,
comparing the weight of a substance of a certain volume to the weight
of the same volume of water.
If you use the metric system which is based on a kilogramm as the
mass of a cubic decimeter of water, your measurement of density of a
substance will be the same number as the specific gravity.
Many greetings, Regina
