Words per minute
Morse code uses variable length sequences of short and long duration "signals" (dots and dashes) to represent source information e.g. sequences for the letter "K" and numeral "2" are respectively () and (). This variability complicates the measurement of Morse code speed rated in words per minute. Using telegram messages, the average English word length is about five characters, each averaging 5.124 dot durations or baud. Spacing between words should also be considered, being seven dot durations in the USA and five in British territories. So the average British telegraph word was 30.67 dot times. So the baud rate of a Morse code is × word per minute rate.
