# Barrel Volume and Surface Area - Metres

Calculate the volume and surface area of a barrel. This calculator uses metres 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 surface area, you must subtract the rim(s) from the height measurement.

##### Approximate weight of Fuel or Water

one litre of water = 1 kilogram
one litre of diesel fuel = 0.832 kilogram
one litre of gas = 0.75 kilogram

#### Calculator

- the barrels' top diameter in metres
- the mid diameter in metres
- the height of the barrel in metres(without the rims)
- the weight of the liquid in kilograms per litre

#### Results

- the volume of the tank in cubic metres
- the volume in cubic centimetres
- the volume in cubic inches
- the volume in cubic feet
- the capacity of the tank in litres
- the capacity in hectolitres
- the capacity in US gallons
- the capacity in Imperial gallons
- full tank liquid weight based on kilograms/L
- the surface area of the tank in square metres
- the surface area in square centimetres
- the surface area in square inches
- the surface area in square feet

##### 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
