How long 1 takes to send

Speed	Unit length	1 takes
5 WPM	240 ms	4.1 s
13 WPM	92 ms	1.6 s
20 WPM	60 ms	1.0 s
25 WPM	48 ms	0.82 s

Standard PARIS timing: one unit is 1200 ÷ WPM milliseconds; a dot is 1 unit, a dash 3, and the gap inside a character 1. Add 3 units between letters and 7 between words.

Easily confused with
