How to use this tool

  1. Enter hose inside diameter, hose length, bucket usable capacity, and water already in bucket in the displayed units.
  2. Calculate and use each labeled result for aquarium hose water inventory. Compare the result with a measured sample before committing materials.

Try this example

{
  "diameter": 16,
  "length": 5,
  "bucket": 10,
  "current": 7
}

Accuracy and scope

Static liquid volume only; not a siphon-rate, drain-system or spill-prevention guarantee. A negative margin means the bucket would be too small.
