Formula for Gallon and Pounds Conversion
How many gallon to lbs?
To convert gallons to pounds of an item, multiply gallons by density of the item
pounds = gallons × density
The density of a substance is its weight per unit of volume. For example, the density of water is 8.34 pounds per gallon.
For example, 5 gallons of water in lbs is equal to 5 * 8.34 = 41.7 lbs
How many lbs to gallons?
To convert from pounds to gallons, divide pounds by density of the item
gallons = pounds / density
For example, 100 pounds of water in gallons is equal to 100 / 8.34 = 12 gallons
Here are a few examples for 1 gallon of some common substances:
- Water: 1 gallon of water = 8.33 pounds
- Milk: 1 gallon of milk = 8.6 pounds
- Gasoline: 1 gallon of gasoline = 6.7 pounds
- Oil: 1 gallon of oil = 7.2 pounds
What is a Gallon?
- The gallon is a unit of volume used to measure liquids.
- The US Gallon is equal to 3.785 liters or 231 cubic inches. Liter is the SI unit to measure volume, Gallon is not an SI Unit.
- The abbreviation used for gallon is 'gal'
- Gallons are the largest measures in the countries that follow imperial / customary system
- There are 2 types of gallons - US Gallon (customary system) and Imperial Gallon (UK) The Imperial Gallon is a larger unit and it is 4.54 liters or 277 cubic inches.

How is a Gallon related to a Pound?
- Gallon is a unit of Volume and Pound is a unit of mass. They are not directly related
- They are indirectly related by Density
- Density of any item is Mass / Volume
- Therefore to find the Mass of an item, multiply Volume with Density. To find Volume given the mass, divide Mass by Density
- Density is usually specified in kg/m3 or in gms/cc. In this case, we have to convert it into lbs/gallon and apply that conversion factor
- Converting gallons to pounds is useful for determining the weight of a specific volume of liquid. Fuel, Engine Oil, chemicals, raw materials in industries are typically sold in gallon containers and it's useful to know the equivalent weight in pounds.
