Density determines conversion
Density is a measure of how much mass a substance has for a given volume. It is expressed in pounds per cubic foot (lb/ft³). The density of a substance determines how many cups are in a pound of that substance.
- Denser substances have more mass per unit volume
For example, lead is denser than water. This means that there is more mass in a cubic foot of lead than there is in a cubic foot of water.
- Less dense substances have less mass per unit volume
For example, air is less dense than water. This means that there is less mass in a cubic foot of air than there is in a cubic foot of water.
- The density of a substance affects how many cups are in a pound
The denser a substance is, the more cups there will be in a pound of that substance. For example, there are more cups in a pound of lead than there are in a pound of water.
- You need to know the density of a substance to convert cups to pounds
In order to convert cups to pounds, you need to know the density of the substance you are measuring. You can find the density of a substance in a reference book or online.
