* Gallons measure volume, which is the amount of space a substance occupies.
* Pounds measure mass, which is the amount of matter in a substance.
To convert gallons to pounds, you need to know the density of the substance you're measuring. Density tells you how much mass is packed into a given volume. Here's the formula:
Mass (in pounds) = Volume (in gallons) x Density (in pounds per gallon)
For example:
* Water has a density of about 8.34 pounds per gallon. So, 100 gallons of water would weigh approximately 834 pounds (100 gallons x 8.34 pounds/gallon).
* Gasoline has a density of about 6.07 pounds per gallon. 100 gallons of gasoline would weigh approximately 607 pounds (100 gallons x 6.07 pounds/gallon).
