Conversion rules

• When entering Morse code, separate characters with one space and words with / or two or more spaces.
• In the Japanese system, hiragana becomes katakana and small kana become full-size kana.
• In the Japanese system, dakuten (..) and handakuten (..--.) are separate codes from the kana.
• The international system does not distinguish upper and lower case.
• Digits use the five-element international codes. The short Japanese digit forms, which overlap with kana codes, are not used.
• Dot and dash lengths are 1:3. Gaps within a character, between characters and between words are 1:3:7, with the dot as the unit.
• Procedural signals (prosigns) are not in the conversion table and cannot be read or generated; codes not in the table are shown as “Unreadable code”.
• You can enter up to 500 characters of text or Morse code, including spaces and line breaks.
