A gematria calculator converts the letters of a word, name, or phrase into numbers and adds them up. The practice began with Hebrew gematria over two thousand years ago, where each letter of the Hebrew alphabet doubles as a numeral — alef is 1, bet is 2, up through tav at 400 — so every word also has a numeric value.
This gematria decoder applies three popular English ciphers at once: English Ordinal (A=1 to Z=26), Full Reduction (the Pythagorean system used in name numerology, where every letter reduces to a digit 1–9), and English Gematria (A=6, B=12 … Z=156). Type any text and you get all three values plus a letter-by-letter breakdown.
What Is Gematria and Where Does It Come From?
Gematria is the practice of assigning numerical values to letters so that words can be compared by their sums. It is best known from Hebrew tradition, where scribes and commentators noted that words sharing a value — such as "ahava" (love) and "echad" (one), both 13 — might share a thematic link. The Greeks used a parallel system called isopsephy, and Arabic has abjad numerals.
English has no native letter-number system, so modern English gematria calculators borrow the idea and map the 26-letter alphabet onto numbers in several standardized ways. None of these ciphers is "official" — they are conventions, and the same word produces a different value in each one. That is why this calculator always labels which cipher a number comes from.
English Gematria Cipher Systems Explained
The three ciphers this english gematria calculator uses are the ones most commonly quoted:
- English Ordinal — A=1, B=2 … Z=26. The simplest and most cited system; "cat" = 3 + 1 + 20 = 24.
- Full Reduction (Pythagorean) — each ordinal value is reduced to a single digit 1–9 (S=19 becomes 1+9=10, then 1). This is the system behind most name numerology calculators.
- English Gematria (A=6) — every ordinal value is multiplied by 6, so A=6, B=12 … Z=156. Sometimes called Sumerian or Agrippa-style numbering; it is the cipher behind many "= 666" word claims.
Because the A=6 value is always exactly six times the ordinal value, any two words that match in one of those ciphers automatically match in the other.
Worked Example: The Gematria of "Love"
Take the word "love" and run each letter through the three ciphers.
- Ordinal: L=12, O=15, V=22, E=5 → 12 + 15 + 22 + 5 = 54.
- Full Reduction: L=3 (12→1+2), O=6 (15→1+5), V=4 (22→2+2), E=5 → 3 + 6 + 4 + 5 = 18.
- English (A=6): 54 × 6 = 324.
So "love" = 54 in English Ordinal, 18 in Full Reduction, and 324 in English Gematria. Any other word summing to 54 in ordinal — "sun" (19+21+14) is one — is called a "match" in gematria circles. Matches are easy to find because thousands of common words share each value, which is worth remembering before reading meaning into them.
Hebrew Gematria: The Original System
Gematria began with Hebrew, where the alphabet doubles as the number system. There are no separate numerals: the letters themselves carry values, running 1–9, then 10–90 in tens, then 100–400 in hundreds. All 22 letters together total 1,495.
Two examples explain why the practice took hold:
- Chai (חי), meaning "life", is chet (8) + yod (10) = 18. This is why 18 is a traditional gift amount in Jewish custom, and why donations often come in multiples of 18
- The Tetragrammaton YHWH (יהוה) is yod (10) + he (5) + vav (6) + he (5) = 26
Because every word carries a number, words sharing a value were treated as connected — a technique used throughout rabbinic literature and later Kabbalah. Note that Hebrew has several counting methods beyond the standard one, including mispar gadol, which gives the five final letter forms values of 500 to 900.
| Letter | Name | Value | Letter | Name | Value |
|---|---|---|---|---|---|
| א | Alef | 1 | ל | Lamed | 30 |
| ב | Bet | 2 | מ | Mem | 40 |
| ג | Gimel | 3 | נ | Nun | 50 |
| ד | Dalet | 4 | ס | Samekh | 60 |
| ה | He | 5 | ע | Ayin | 70 |
| ו | Vav | 6 | פ | Pe | 80 |
| ז | Zayin | 7 | צ | Tsadi | 90 |
| ח | Chet | 8 | ק | Qof | 100 |
| ט | Tet | 9 | ר | Resh | 200 |
| י | Yod | 10 | ש | Shin | 300 |
| כ | Kaf | 20 | ת | Tav | 400 |
This is mispar hechrachi, the standard absolute value method. The calculator above works with English ciphers — use this table to work Hebrew words out by hand.
Greek Isopsephy and the Number 666
A Greek gematria calculator works on the same structure, though in Greek the practice is called isopsephy rather than gematria. Alpha is 1 through theta at 9, iota is 10 through koppa at 90, and rho is 100 through sampi at 900. Three archaic letters — digamma (6), koppa (90) and sampi (900) — survived as numerals after dropping out of the written alphabet.
The most famous isopsephy in existence is 666, the "number of the beast" in Revelation 13:18, which the text itself presents as a number to be worked out. In Greek numerals it is written chi (600) + xi (60) + digamma (6) = 666.
The most-cited interpretation reads it as a transliteration of "Nero Caesar" into Hebrew letters, which sums to 666 — and notably, some early manuscripts give the number as 616, which matches an alternative Latin spelling of the same name. That variance is itself evidence the number was understood as encoding something.
Which Gematria Cipher Should You Use?
There is no single correct cipher, which is the honest answer to why the same word returns different numbers on different sites. The English systems in common use:
- English Ordinal (A=1, B=2 … Z=26): the simplest and most widely used
- Full Reduction (A=1 … I=9, then J restarts at 1): compresses everything to 1–9, the same digit-sum logic as numerology
- English Gematria (A=6, B=12 … Z=156): the ordinal value multiplied by 6. A Jewish gematria calculator usually means this cipher, sometimes also labelled Sumerian, chosen so that "Jesus" returns 444 and other figures land on repeating digits
- Reverse ciphers: the alphabet run backwards, so A=26 and Z=1
The calculator above returns Ordinal, Full Reduction, and English (A=6) together, letter by letter, so you can see how each value is built rather than just the total.
A word of caution about method: with several ciphers available and no rule for choosing between them, it is easy to test a phrase against each until one produces a striking number. That is selecting the result after seeing the data, and it will find patterns in any text — including randomly generated ones.
Frequently Asked Questions
What is a Hebrew gematria calculator and can I use this one?
A Hebrew gematria calculator sums the numeric values of Hebrew letters, where alef is 1 through tav at 400. The calculator on this page handles English ciphers — Ordinal, Full Reduction, and English (A=6). For Hebrew, use the letter-value table above: chai (חי) is 8 + 10 = 18, and YHWH (יהוה) is 10 + 5 + 6 + 5 = 26.
What is simple gematria?
Simple gematria, also called English Ordinal, assigns A=1 through Z=26 and adds the letters. "Love" is 12 + 15 + 22 + 5 = 54. It is the most common English cipher and the first value the calculator returns.
How does Greek gematria work?
Greek isopsephy assigns alpha=1 through theta=9, iota=10 through koppa=90, and rho=100 through sampi=900. Its best-known result is 666 in Revelation, written chi (600) + xi (60) + digamma (6).
Why do different gematria calculators give different numbers?
Because they use different ciphers. The same word can return one value in English Ordinal, another in Full Reduction, and a third in English (A=6), which is simply the ordinal value multiplied by 6. None is more correct than the others — always check which cipher a result came from.
What is a gematria decoder?
Just another name for a gematria calculator — a tool that converts letters to their numeric values and totals them. This page decodes any word or phrase into three English ciphers at once, showing each letter’s contribution.
What does my name equal in gematria?
Type your name into the calculator to get three values instantly. As a quick example, "Anna" equals 30 in English Ordinal (1+14+14+1), 12 in Full Reduction, and 180 in English (A=6) gematria. First name, full name, and nicknames all produce different numbers, so state which form you used when quoting a value.
What is the difference between Hebrew gematria and English gematria?
Hebrew gematria is the original system: Hebrew letters are actual numerals (alef=1 through tav=400), so values are built into the language. English gematria is a modern adaptation that maps the 26 English letters onto numbers using invented ciphers such as Ordinal (A=1) or A=6. Hebrew values are fixed by tradition; English values depend entirely on which cipher you pick.
How do you calculate gematria by hand?
Write out the word, assign each letter its number, and add. For English Ordinal use A=1, B=2 … Z=26. For example, "abc" = 1 + 2 + 3 = 6. For Full Reduction, first reduce any two-digit letter value to one digit (T=20 → 2). For English (A=6) gematria, simply multiply the ordinal total by 6, so "abc" = 36.
What is the gematria value of 666 in the A=6 cipher?
In the English (A=6) cipher, any word whose ordinal value is 111 equals 666, because the A=6 value is always the ordinal value times six. Hundreds of everyday English words sum to 111 in ordinal, which is why so many unrelated words "equal 666" — it is a mathematical consequence of the cipher, not a hidden signal.
Is gematria real or just for entertainment?
Gematria is a real historical practice with a documented role in Hebrew scholarship and mysticism, but the numbers themselves carry no predictive or scientific power. Because thousands of words share every common value, matches are statistically inevitable. Treat English gematria results as a fun linguistic curiosity or a window into history, not as evidence of hidden meaning.
