Beneath every word in the Hebrew Bible lies a number — gematria is the ancient method of revealing it. Jewish scholars, Kabbalistic mystics, and early Greek and Christian writers used these systems to uncover hidden connections in sacred texts.
A gematria calculator instantly converts any word, name, or phrase into numerical values across multiple cipher systems, using verified tables from Hebrew, Greek, and English traditions — no sign-up, no limits.

What Is Gematria?
An alphanumeric cipher system in which each letter carries a fixed numerical value. Sum those values across a word and the result is its numerical equivalent. When two words share the same total, that connection is treated as meaningful in Jewish, Kabbalistic and early Christian scholarship.
A History Spanning Two Thousand Years
The system has a documented history stretching back more than two thousand years. The earliest Hebrew usage appears in Talmudic literature, where numerical equivalence between passages — a method called gezera shava — was used to draw interpretive parallels that direct translation cannot reveal. The Zohar and Sefer Yetzirah, the foundational texts of Kabbalah, use this alphanumeric method throughout.
The Greek Parallel — Isopsephy
Its Greek counterpart is called isopsephy. Pythagorean philosophers applied identical letter-number logic to the Greek alphabet, and early Christian writers continued the tradition — the number 888, the Greek alphanumeric sum of Iesous (Jesus), appears as a deliberate counterpoint to 666 in second-century theological writing.
How It Differs from Numerology
Modern numerology reduces all totals to a single digit through repeated addition — 47 becomes 4+7 = 11, then 1+1 = 2. Classical alphanumeric ciphers preserve the full sum. In Kabbalistic tradition, 47, 470 and 4,700 are each distinct values with separate interpretive histories.
How to Use This Calculator
Step 1 — Enter your text. Type any word, name or phrase into the input field. The tool accepts English, romanized Hebrew, native Hebrew characters and classical Greek. Letter-value tables load automatically for the detected script.
Step 2 — Read all ten cipher totals instantly. Every value updates character by character — no submit button required. All ten encoding systems display side by side so you can compare traditions in a single view.
Step 3 — Switch between cipher systems. Select any system from the panel and the total recalculates immediately. Researchers cross-referencing a Hebrew phrase with its Greek New Testament parallel can check both within the same session.
Step 4 — Run a reverse lookup. Enter a number instead of text. The tool returns every word, name and phrase in the database that reaches that value under any cipher — the standard research method for investigating numbers like 33, 144, 322, 666 or 888 across traditions.
The Ten Cipher Systems
Hebrew Standard (Mispar Hechrachi) — The classical Kabbalistic assignment from the Talmud and Sefer Yetzirah. Aleph = 1 through tav = 400, extended to 900 through the five sofit (final-letter) forms. The primary cipher in Zoharic and rabbinic commentary.
Hebrew Ordinal (Mispar Siduri) — Sequential values 1–22 assigned to the 22 Hebrew consonants, prioritising letter position over traditional positional weight.
English Ordinal — A = 1 through Z = 26. The most direct Latin-alphabet parallel to Hebrew standard assignment and the most widely used English cipher in contemporary alphanumeric research.
English Reduction (Pythagorean) — Each letter reduces to a single digit in a nine-cycle pattern. Draws on the same logic applied in classical Pythagorean numerological analysis.
Reverse Ordinal — Z = 1 through A = 26. Inverts the standard ordinal scale; used as a cross-check cipher in comparative analysis.
Reverse Reduction — Single-digit reduction applied to reversed ordinal values. Often paired with Pythagorean reduction for pattern verification.
Sumerian Cipher — Each ordinal position multiplied by 6: A = 6, Z = 156. This sexagesimal (base-60) scale connects to Babylonian numerical tradition and appears in Western esoteric schools.
Francis Bacon Cipher — A 52-value system distinguishing uppercase and lowercase letters: a = 1 through z = 26, then A = 27 through Z = 52. Used in Elizabethan-era alphanumeric and literary cipher research.
Jewish Gematria — A non-sequential table designed to preserve Hebrew letter weights when applied to English-spelled Hebrew words and proper names.
Greek Isopsephy — The historically documented values of all 24 classical Greek letters: alpha = 1 through omega = 800, with koppa = 90 and sampi = 900 in the extended system. The cipher used to analyse 666 in the original Koine Greek text of Revelation 13:18.
Who Uses This Tool
Bible researchers and theologians use letter-value analysis to identify numerical parallels in original Hebrew and Greek texts — connections that translation removes entirely. In traditional Talmudic scholarship, two passages sharing the same alphanumeric total carry genuine interpretive weight.
People exploring their own name arrive wanting to know what their name means numerically in Hebrew or whether it connects to a word or phrase in scripture. Running a name through multiple encoding systems simultaneously — then using the reverse lookup to see what else shares that value — opens research that a single cipher alone would miss.
Students of Kabbalah and Jewish mysticism use the tool as a live arithmetic reference while reading the Zohar or Sefer Yetzirah, verifying word totals without interrupting the session to work through a printed letter chart.
Researchers in Western esoteric traditions work primarily with English-alphabet encoding systems — ordinal, reduction and Sumerian variants — and need several ciphers visible at once to identify which table produces the value they are investigating.
Frequently Asked Questions
How is a word's numerical value calculated?
Each letter is assigned its value from the selected encoding table. Those individual values are summed. The total is the word's numerical equivalent. The process is identical across all ten systems — only the letter-to-number table changes.
What is the difference between Hebrew gematria and Greek isopsephy?
Both assign fixed numbers to alphabet letters and sum those values to analyse words. Hebrew tradition uses the 22-letter Hebrew alphabet with values from Talmudic sources. Isopsephy uses the 24-letter classical Greek alphabet with historically documented values. The two traditions developed in parallel and are often used together in New Testament research.
What is the numerical value of 666?
In Greek isopsephy, 666 is the value of χξϛ (chi xi stigma) as written in Revelation 13:18. The reverse lookup in this tool returns every word, name and phrase in the database that reaches 666 under any active cipher.
What does 888 represent?
888 is the Greek isopsephy value of Iesous — the Greek form of Jesus — documented in second-century Christian texts as a deliberate numerical counterpoint to 666. It is among the most studied values in New Testament alphanumeric research.
Can I search by number instead of text?
Yes. Enter any integer and the tool returns every matching word, name and phrase across all active ciphers. This reverse lookup is the standard research method for any specific number.
