KPH, explained
Keystrokes per hour is the speed unit for 10-key and data entry jobs. Tests rarely last an hour, so the score is scaled up from a few minutes.
The formula
KPH = keystrokes ÷ minutes × 60
Example: 450 keystrokes in 3 minutes is 450 ÷ 3 × 60 = 9,000 KPH.
Gross vs. net
Gross counts every key pressed. Net (also called corrected) counts only the keys that ended up right. If you key 450 and 30 of them are wrong in the records you submit, gross is 9,000 KPH and net is 420 ÷ 3 × 60 = 8,400 KPH.
Postings differ on which one they mean. The 2018 Orange County posting says “corrected rate”; the 2026 Gahanna posting just says keystrokes per hour “with minimal error”. When a posting doesn't say, assume the stricter one — net.
Does Enter count?
On this site, yes: Enter ends a record and counts as one keystroke. Other tests may count it differently, so a score from one test may not match another to the keystroke. How we score lists every rule we use.
KPH and WPM
By the usual convention a “word” is 5 characters, so the arithmetic is KPH = WPM × 5 × 60 (40 WPM → 12,000 characters per hour). That's only arithmetic. Typing text and keying numbers on a keypad are different skills, and we haven't found an employer that treats the two as interchangeable.
