# Calculate Liters in a Bucket

## Calculator how many liters fit in a bucket of a certain size or how much is in the bucket at a certain fill level.

Mathematically, a round bucket is a truncated cone. The size of the bucket is specified by the diameters at the bottom and top and the height, the volume is h * π / 12 * (D² + Dd + d²) with the height h, the lower diameter d and the upper one Diameter D. Lengths must be measured inside the bucket if the bucket wall has a notable thickness.

Example: a bucket with a bottom diameter of 30 cm, an opening of 33 cm and a height of 25 cm has a capacity of almost 19.5 liters.

Please enter both diameters and the height of the bucket. The volume will be calculated.

If the bottom diameter is 0, then it is a cone.

Example of a partially filled bucket: The bucket above is filled up 13 centimeters. It contains almost 9.7 liters, the filling width is 31.56 centimeters, the bucket is not quite half full.

Please enter both diameters, the height and the fill level of the bucket. Volume, filling width and filled fraction will be calculated.

The fill width is the diameter of the bucket at the fill level. It is calculated as d + ( D − d ) * f / h with f as the fill level. For the calculation of the volume, use the fill level instead of the height and the filling width instead of the mouth diameter.

This plastic bucket has an opening of 25.8 cm, a base diameter of 19.5 cm and a height of 25 cm, so it holds approximately 10.1 liters of water. If it is filled up to 20 cm, then it is about three quarters full. The top mark in this bucket indicates 10 liters.

Here you can convert metric volume units into customary and imperial units.
