The Full Form of KDPH is‍ Key Depressions Per Hour.

The term ‘Key depression’ is used for the typing speed and the term ‘Words per Minute’ is used to measure the reading speed.

Key depressions per hour = 5000

Key depression per minute = 5000/60

= 83 key depressions per minute (Approximately)

When converting it into word per minute, the language in question plays an important.

In English, an average word consists of 4 – 5 characters. If we calculate with 4, then the equation is as follows.

⇒ 4x + x – 1 = 83

(x refers to the number of words and x – 1 refers to the number of spaces between words, which also counts as the total number of key depressions)

⇒ 5x = 83 + 1

⇒ 5x = 84

⇒ x = 84/5

⇒ x = 16.8 words per minute.

Calculation with 5 letters in a word –

⇒ 5x + x – 1 = 83

⇒ 6x = 83 + 1

⇒ 6x = 84

⇒ x = 84/6

⇒ x = 14 words per minute.
