Cubic feet are abbreviated ft^3, cu ft. or cf and barrels are abbreviated bbl, brl or bl. Both units measure volume. The cubic foot is used in most English-speaking countries. The barrel is often used to measure beer and wine. Since both units measure the same quantity, you can convert directly between the two. For example, if you have a measurement of volume in cubic feet, and want to compare the quantity to a volume in barrels, you would need to convert.
