WPM, CPM, and KPH answer different questions
WPM uses five typed characters, including spaces, as one conventional word. CPM is a derived explanatory conversion from correct final characters per active minute, not a separately displayed TypeWorkout result. KPH is keystrokes per active hour and is more useful for structured numeric entry. These units are related calculations, not interchangeable benchmark labels.
Benchmark by goal, not by leaderboard
For prose, establish a repeatable WPM baseline. For data entry or 10-key work, use the exact KPH rules and include separators. For coding, email, or transcription, use the matching text and duration. A useful benchmark is a comparison under the same conditions, not a universal cutoff.
Compare like with like
Compare results only when test duration, language, punctuation, correction rules, and keyboard layout are similar. A 15-second sprint and a five-minute work passage are not interchangeable, and a group comparison can reflect hardware or text differences as much as skill.
Accuracy changes the meaning of speed
Accuracy is correct key attempts divided by all key attempts. High raw speed with frequent corrections may produce less finished output than a slightly lower net speed with clean entry, so report accuracy with the headline result.
Use job requirements carefully
When an employer provides a threshold, practice the same task format and duration. Do not assume a general web test reproduces a validated hiring assessment, and do not present this guide's comparisons as population statistics.
