Barrel

Barrel

Calculate the volume, capacity, and surface area of a barrel. This calculator uses inches for measurements.

Barrels usually have rims (chimes) on the top and bottom.

The barrel's volume is calculated from inside measurements, and you must deduct the rims from your height measurement. The same applies to the surface area. Calculating the amount of wood in contact with the liquid inside the barrel, you must subtract the rim(s) from the height measurement.

Formula
V = 𝝅H/15(3T²+8M²+4TM)
where V is the volume of the cone
𝝅 = 3.14159265
T the  top diameter divided by 2
M the mid diameter divided by 2
H the height of the barrel
