Question 1

Is a quart always equal to a pound?

Accepted Answer

No. A quart is a measure of volume and a pound is a measure of mass. The weight depends entirely on the density of the substance.

Question 2

Why do I need to know the density?

Accepted Answer

Since different materials have different weights per unit volume (e.g., oil is lighter than water), the density constant is required to get an accurate conversion.
