Questions & answers
What does Container Fill Percentage Calculator calculate?
Calculate fill level and remaining capacity for a straight-sided container.
Which units should I enter?
Full height uses cm. Liquid height uses cm. Total capacity uses liters. Convert values to these units before calculating.
Which formula does it use?
For a constant cross-section, volume fraction = liquid height/full height.
What does the included example show?
Full height: 40 cm; Liquid height: 25 cm; Total capacity: 20 liters. Result: Filled · percent = 62.5; Liquid volume · liters = 12.5; Remaining capacity · liters = 7.5.
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.
