How the calculation works
Completion = transferred quantity ÷ total quantity × 100. Use the same size units for both values. Transferred quantity must be from zero to the positive total; inconsistent values are rejected. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Uploaded Amount = 25; Total File Size = 100; File Size Unit = "MB". Result: 25%.
Practical tip
