Why is density important?

Measuring density is very important for many different industries because the density measurement will help determine the characteristics of a material, for example, whether the material will float or sink. Knowing the density of a material helps in determining the mass and volume of a material, all of which are extremely important measurements in all industries.

The density of a material is the mass of the material divided by its volume. If, for instance, a company wants to manufacture a boat or aircraft, the company will rely heavily on measuring the density of its materials to know if a boat will float or if an aircraft will fly.
