How the calculation works

Duration = words ÷ words per minute; convert to seconds for display. Rate must be positive and means words per minute. The rate stays constant for the estimate. The model does not assess error density, revisions, fact checking, specialist review or the number of editing passes. A plain duration is minutes; labelled h, min, sec and d are also accepted. One duration day is 24 hours. Results round to the nearest second, and a positive duration below half a second is labelled Less than 1 sec. Entered decimal arithmetic is applied before display rounding. Numeric inputs/results and durations in seconds are bounded by magnitude 9,007,199,254,740,991.
