TERMINOLOGY:
PARIS Word Length: By convention in the Amateur
industry (utilized by ARRL and others), the length of
one “word” of CW is defined as the length of the Morse
Code characters spelling the word “PARIS.” This char-
acter (dot/dash/space) length is used for the stan-
dard definition of code speed in “words per minute”.
