Calculate the volume, capacity, and surface area of a barrel. This calculator uses millimetress for measurements.
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.
one litre of water = 1 kilogram one litre of diesel fuel = 0.832 kilogram one litre of gas = 0.75 kilogram
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
