Morse Code Converter

Morse code encodes text using sequences of dots (dits) and dashes (dahs) representing letters and numbers. Developed in the 1830s for telegraph communication, it remains in use in: aviation (VOR/NDB radio beacons transmit their identifier in Morse), amateur (ham) radio operations, military signalling, and accessibility applications for people with motor disabilities.

SOS is · · · − − − · · · (three dots, three dashes, three dots). It was chosen as an international distress signal because of its simplicity and distinctive rhythm — not because it stands for "Save Our Souls" or any phrase. The letters S (· · ·) and O (− − −) are among the easiest to learn.

WPM in Morse is standardised using the word PARIS (50 dot-units long) as the reference. At 15 WPM: a dit lasts 80ms, a dah is 3× longer (240ms). The gap between symbols within a letter is 80ms; between letters 240ms; between words 560ms. Increasing WPM proportionally shortens all timing.

Yes — use the audio playback feature to train your ear to recognise the sound patterns for each letter. Most Morse learners start with the most common letters (E · T − I · · A · − N − · M − −) before moving to less frequent ones. The built-in reference chart shows all letter, number, and punctuation codes.
