How to Calculate Truncated Cone Volume in Imperial Units

Determine frustum volume in gallons and cubic feet. Enter top diameter, bottom diameter, and height in inches or feet.

Example: a conical hopper 4 ft top, 1.5 ft bottom, and 5 ft tall holds about 285 gallons. A tapered planter 8 inches top, 5 inches bottom, and 7 inches tall holds roughly 0.8 gallons.

Used for hoppers, funnels, conical tanks, and tapered containers.
