Morse Code Translator
Convert text to International Morse Code and decode Morse code sequences into readable text.
Quick Answer & Understanding Your Result
A Morse Code Translator converts plain text characters into standardized International Morse Code (ITU-R M.1677) dot-dash sequences (`.` and `-`) and decodes Morse signals back to readable English with 0ms latency.
The ITU-R M.1677 Timing Standard
- Dot / Dit (`.`): The basic fundamental unit of time measurement (1 time unit).
- Dash / Dah (`-`): Exactly three times the duration of a single dot (3 time units).
- Intra-Character Space: Pause between dits and dahs within the same letter (1 time unit).
- Inter-Character Space: Pause between consecutive letters (3 time units).
- Inter-Word Space (` / `): Pause between separate words (7 time units).
Aviation, Maritime & Amateur Radio Applications
- Emergency Distress Signaling: Transmitting SOS (
... --- ...) and maritime emergency beacons. - Ham Radio (CW Transmission): Long-range low-bandwidth telegraphy communications.
Enter your text or Morse code above to translate bidirectional streams and inspect dot/dash timing units.
Formula & Calculation Logic
Mathematical FormulaTranslates standard alphanumeric characters and punctuation into international radio telegraphy Morse code sequences and calculates transmission duration units.
Step-by-Step Guide
Enter Text or Morse Code
Type regular text (e.g. SOS MAYDAY) or paste dot-dash sequences (e.g. ... --- ...).
Select Conversion Direction
Use 'Auto-Detect' or explicitly choose 'Text to Morse Code (Encode)' or 'Morse Code to Text (Decode)'.
Choose Word Separator Format
Select standard Slash ' / ', Triple Space, or Pipe ' | ' between words.

Worked Examples Table
| Example | Input Values | Calculated Result | Explanation |
|---|---|---|---|
| International Distress Signal (SOS) | 3 dots for S, 3 dashes for O, and 3 dots for S. | ||
| Decode 'HELLO WORLD' | Decodes dot-dash sequences into plain English capital letters. |
