Enter one known typing rate
Words per minute, keystrokes per minute, and keystrokes per hour describe the same rate in different units. Select the one unit you know and enter one value; the calculator derives the other two instead of presenting three circular editable fields.
Convert with a standard word length
With the published five-keystroke standard, KPM equals WPM multiplied by 5, and KPH equals KPM multiplied by 60. In reverse, KPM equals KPH divided by 60 and WPM equals KPM divided by the selected keystrokes per standard word.
Reproduce the published examples
At 18 WPM and five keystrokes per standard word, the rate is 90 KPM and 5,400 KPH. A rate of 8,000 KPH is 133.333 KPM and 26.667 WPM under the same standard.
Project a session without changing the rate
Session keystrokes equal KPM multiplied by session minutes, and projected standard words equal WPM multiplied by session minutes. This is a gross continuous-rate projection; breaks, warm-up, corrections, fatigue, formatting, and task complexity can reduce actual output.
Keep gross speed separate from accurate productivity
The five-keystroke word is a normalization convention, not a claim that every real word has five characters. Tests may count spaces, punctuation, corrections, or errors differently. Compare results only when the word definition, timing interval, error treatment, keyboard, language, and task are consistent.
