About Morse Code

Morse code encodes text as sequences of dots (·) and dashes (−), originally transmitted as electrical pulses. Developed by Samuel Morse and Alfred Vail in the 1830s, it became the global standard for radio communication throughout the 20th century. Each letter maps to a unique pattern: E is a single dot, T is a single dash, and SOS (the universal distress signal) is ··· − − − ···. This translator supports all 26 letters, digits 0–9, and common punctuation. The bidirectional translator works both ways — type text on the left to see Morse on the right, or type valid Morse code on the right to decode it to text. WPM (words per minute) is calibrated using the standard word "PARIS" (50 dot-units). At 13 WPM, a dot lasts approximately 92 ms. Audio uses the browser's Web Audio API — no plugins or downloads required.

Frequently Asked Questions

How do I read Morse code?
Each letter is represented by a sequence of dots (·) and dashes (−). A single dot is E, a single dash is T. Letters are separated by a space, words by a slash (/).
What is WPM in Morse code?
WPM (words per minute) is based on the standard word "PARIS" (50 dot-units long). At 13 WPM — typical for beginners — a dot lasts about 92 milliseconds.
What does SOS look like in Morse code?
SOS is ··· − − − ··· (three dots, three dashes, three dots). It was chosen because it's easy to recognize, not because it stands for a phrase.
How long does it take to learn Morse code?
With daily practice using the Koch method, most beginners can copy at 5–10 WPM within 2–3 months.
