Convert text to Morse code and Morse code to text. Includes audio playback, timing calculations, WPM speed adjustment, and a complete reference table.
The Morse Code Translator converts text to Morse code and vice versa, with timing calculations and a complete reference chart. Morse code, developed by Samuel Morse and Alfred Vail in the 1830s, encodes characters as sequences of dots (dits) and dashes (dahs), and remains relevant today in amateur radio, aviation, emergency signaling, and accessibility applications.
This tool handles the full International Morse Code standard, including all 26 letters, 10 numerals, and common punctuation marks. You can adjust the words-per-minute (WPM) speed to calculate precise timing for each element—a critical detail for radio operators and anyone learning to send or receive Morse. The standard PARIS timing method defines one word as 50 dot-lengths, making timing calculations straightforward.
Beyond simple conversion, this translator shows character-by-character breakdowns, calculates transmission time at your chosen speed, counts dots and dashes, and provides a complete reference table. Whether you're studying for a ham radio license, building a Morse code project, or just curious about this enduring communication system, this tool has you covered.
Learn Morse code, calculate transmission times, or convert messages for amateur radio, emergency signaling, and educational projects.
This tool is useful because it combines translation with timing. Seeing the code pattern, WPM speed, and total send time together is much more useful than a plain dot-dash lookup when you are actually practicing or planning a signal.
Dot duration = 1.2 / WPM seconds (PARIS standard). Dash = 3 × dot. Intra-character gap = 1 dot. Inter-character gap = 3 dots. Inter-word gap = 7 dots. Total time = sum of all element durations.
Result: ... --- ... (transmission time: 1.26 seconds at 20 WPM)
S = three dots (···), O = three dashes (---), S = three dots (···). At 20 WPM, each dot is 60ms, each dash is 180ms, with appropriate gaps between elements.
Samuel Morse and Alfred Vail developed the telegraph and its code in the 1830s-1840s. The original American Morse Code was later superseded by International Morse Code, standardized in 1865. For over a century, Morse code was the primary long-distance communication method, used in telegraphy, maritime communication, and early radio. The famous "What hath God wrought" message was sent by Morse in 1844.
Precise timing is the foundation of readable Morse code. At the standard PARIS calibration, 1 WPM means each dot lasts exactly 1.2 seconds. At 20 WPM (a common operating speed), dots are just 60 milliseconds. The ratio between elements is always constant: dash = 3 dots, character gap = 3 dots, word gap = 7 dots. Mastering this rhythm is essential for both sending and receiving.
Despite being a 19th-century invention, Morse code remains surprisingly relevant. Amateur radio operators worldwide communicate via CW (continuous wave) Morse, which requires less bandwidth and power than voice. Pilots use Morse identifiers on navigation beacons. Accessibility devices allow people with severe disabilities to communicate using just two inputs (dot and dash). Some smartphone apps even convert notifications to Morse-code vibrations.
Beginners typically start at 5 WPM, proficient operators work at 15-25 WPM, and experts can exceed 40 WPM. The minimum for a US amateur radio license was historically 5 WPM (now removed).
SOS (··· --- ···) is the international distress signal. It was chosen because it's easy to recognize and send, not as an abbreviation. It's transmitted as a single character without gaps.
A dash (dah) is exactly 3 times the duration of a dot (dit). The gap between elements within a character is 1 dot length, between characters is 3 dot lengths, and between words is 7 dot lengths.
Yes! Amateur radio operators use it worldwide, aviation uses it for navigational aids (VOR/NDB), the military uses it in some applications, and it's used in accessibility devices for people with limited mobility.
PARIS is the standard word used to calibrate Morse code speed. The word PARIS in Morse code is exactly 50 dot-lengths, so WPM speed means "how many times PARIS can be sent per minute."
International Morse Code covers Latin letters, numbers, and basic punctuation. Extensions exist for Cyrillic, Arabic, Japanese (Wabun code), and other scripts, but they're not part of the core standard.
