How to Calculate Barrel Volume in Imperial Units

This calculator computes barrel water capacity in US gallons and cubic feet. Enter barrel height and diameter in inches or feet to determine how much liquid it holds.

Example: a standard 55-gallon drum is 33.5 inches tall with a 23-inch diameter. A traditional wine barrel (barrique) holds about 59 US gallons (7.9 ft³).

Supports both cylindrical and curved-side barrel profiles. Results display in fluid ounces, gallons, and cubic feet.
