How to use this tool

  1. Enter funnel inside diameter, collected water, and gauge displayed depth in the displayed units.
  2. Calculate and use each labeled result for rain gauge catch calibration. Compare the result with a measured sample before committing materials.

Try this example

{
  "diameter": 10,
  "volume": 78.54,
  "display": 10
}

Accuracy and scope

Assumes all funnel water reaches the vessel without leakage or evaporation; wind and splash bias are excluded.
