Detailed Answer
CPM stands for 'Characters Per Minute' – the raw count of keystrokes typed in one minute. It includes every letter, number, punctuation, space, and sometimes symbol. CPM is useful for tasks requiring exact character accuracy (e.g., coding, data entry). To convert WPM to CPM: multiply WPM by 5 (since 1 word = 5 characters). For example, 40 WPM = 200 CPM. However, CPM often ignores errors unless specified as 'Net CPM' (only correct characters). Many typing tests display both WPM and CPM to give a complete picture of raw speed.
