2018-2-26 · What is density? Density is a characteristic property of a substance. • The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Specific gravity is a unitless measurement. Density equals the mass of the substance divided by its volume; D = m/v. Density measurement gives useful information about composition, the …

Density Measurement for Industrial Applications

Density Measurement for Industrial Applications

A material's density is defined as its mass per unit volume. Put another way, density is the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" an object has in a unit volume (cubic meter or cubic centimeter). Density is essentially a measurement of how tightly matter is crammed together.
