How do you convert keystrokes per hour to WPM?

Convert keystrokes per hour to words per minute by dividing keystrokes per hour by 250. According to Coleman Data Solutions, the approximate ratio between keystrokes per hour and words per minute, or WPM, is 250 to 1.

Coleman Data Solutions shows that 250 times the words per minute equals a typist's keystrokes per hour. This is because an average operator types for 50 minutes during a workday hour, and the average number of characters per typed word is five. Keystrokes per hour and words per minute are useful statistics for measuring the speed and accuracy of operators performing various types of data entry in the workplace.
