Common Questions

Is density the same as weight?

No. Density is mass divided by volume. Weight is a force caused by gravity, so objects with the same density can have very different weights when their sizes differ.

Why does specific gravity have no unit?

Specific gravity is a ratio between a material density and a reference density. Because the matching units divide out, the result is dimensionless.

Can a material have more than one density?

Yes. Temperature, pressure, moisture, composition, and manufacturing differences can change actual density. Reference values are representative, not universal.
