How to use this tool

  1. Enter the measured quantities and your own planning assumptions.
  2. Review all calculated outputs and the stated limitations.

Try this example

{
  "start": 120.1,
  "end": 120.13,
  "hours": 6,
  "tariff": 3
}

Accuracy and scope

Assumes no legitimate water use during the observation and a constant loss rate. Meter rounding can dominate small readings.
