How Do You Calculate Gallons Per Cubic Foot?
Gallons and cubic feet are two ways to measure volume. Typically, gallons are used to measure liquids, while cubic feet are generally used for solids, but they are technically interchangeable. For example, if you were buying an aquarium and one model listed the size of its tank in gallons and another listed the size of the tank in cubic feet, you would have to convert the gallons to cubic feet to compare the two tanks. Determine the number of gallons you want to convert to cubic feet. For example, if you were converting the volume of a fish tank, you would check the specifications of the tank. Multiply the number of gallons by 0.1336 to convert to cubic feet. For example, if the aquarium was 20 gallons, you would multiply 20 by 0.1336 to find the volume equals 2.67 cubic feet. Divide the number of gallons by 7.48 as a way to check your answer. You can use either the method in Step 2 or this step to find the answer. Finishing the example of the 20-gallon tank, you would divide 20 by 7.4
