Which units should I enter?
Flow rate uses liters per minute. Minutes per use uses minutes. Uses per day uses uses. Days uses days. Convert values to these units before calculating.
Which formula does it use?
Volume = flow × duration × uses × days.
What does the included example show?
Flow rate: 8 liters per minute; Minutes per use: 7 minutes; Uses per day: 2 uses; Days: 30 days. Result: Volume per use · liters = 56; Daily volume · liters = 112; Period volume · cubic meters = 3.36.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
