Questions & answers
What does Tank Refill Time Calculator calculate?
Estimate refill time using volume and constant flow.
Which units should I enter?
Target volume uses liters. Current volume uses liters. Flow rate uses liters per minute. Convert values to these units before calculating.
Which formula does it use?
Minutes = (target − current)/flow; flow is assumed constant.
What does the included example show?
Target volume: 200 liters; Current volume: 40 liters; Flow rate: 12 liters per minute. Result: Volume to add · liters = 160; Refill time · minutes = 13.333333.
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.
