FormulaMachine water with whole cycles = Math.ceil(settings/capacity)*machine; Hand-washing water = settings*hand; Settings needed to match one cycle water = Math.ceil(machine/hand)

Made for real tasks

  • Compare measured hand-washing water use with machine cycles at the same number of place settings.
  • Compare an alternative set of measurements without uploading personal data.

How to use this tool

  1. Enter water per machine cycle, place settings per full cycle, measured hand-wash water per setting, and settings to wash in the displayed units.
  2. Calculate and use each labeled result for dishwashing water break-even. Compare the result with a measured sample before committing materials.

Try this example

{
  "machine": 10,
  "capacity": 12,
  "hand": 2,
  "settings": 30
}

Accuracy and scope

Water comparison only; actual loading, pre-rinsing, electricity, detergent and cleaning performance are excluded.
