Gematria Calculator (Hebrew & English)
Calculate gematria values for any word or phrase using six classical systems: Hebrew Standard, Hebrew Ordinal, English Ordinal, English Standard (Jewish Cipher), Pythagorean Reduced, and Greek isopsephy.
RELIGION · SOCIALGematria assigns numerical values to letters and sums them for a word or phrase. This calculator supports six traditions: Hebrew Standard (Mispar Hechrachi, aleph=1, yud=10, qof=100, tav=400), Hebrew Ordinal (position 1-22), English Ordinal (A=1..Z=26), English Standard / Jewish Cipher (A=1..I=9, J=10..R=90, S=100..Z=400), English Reduced / Pythagorean (1-9 cycle), and Simple Greek isopsephy (alpha=1..omega=800). Type any word and compare how it scores across methods.
Each method uses its own lookup table. Hebrew Standard treats letters as a base-10 ladder: aleph through tet are 1-9, yud through tsadi are 10-90, qof through tav are 100-400. The Hebrew word chai (חי, 'life') = chet (8) + yud (10) = 18, which is why 18 is a symbolic number for life in Jewish tradition (gifts in multiples of 18). Shalom (שלום) = 300 + 30 + 6 + 40 = 376. In English Standard / Jewish Cipher, Jesus = J(10) + e(5) + s(100) + u(300) + s(100) = 515; God = G(7) + o(60) + d(4) = 71. In English Ordinal, Love = L(12) + o(15) + v(22) + e(5) = 54. Greek isopsephy follows the same base-10 ladder: Ιησους (Iesous) = 10 + 8 + 200 + 70 + 400 + 200 = 888, a number long discussed in early Christian texts. Spaces, punctuation, and digits are skipped automatically.

About Gematria
Gematria is an ancient practice of assigning numerical values to letters and computing the sum for a word or phrase. The Hebrew tradition is most associated with Kabbalistic and Talmudic interpretation, where two words sharing a value were sometimes read as conceptually linked. The Greek parallel, called isopsephy, appears in classical inscriptions and in the New Testament (Revelation 13:18 — the number 666). English numerology systems emerged later, drawing on both Hebrew patterns and esoteric Christian and occult traditions in the 17th-20th centuries.
The four widely-used English methods differ in their letter-to-number mapping. Ordinal is the most intuitive: A=1, B=2, ... Z=26. English Standard (also called Jewish Cipher or simply "English Gematria") mirrors the Hebrew pattern: A=1 through I=9, then J=10, K=20, ... R=90, then S=100, T=200, ... Z=400. Pythagorean Reduced cycles 1-9 across the alphabet: A=1..I=9, J=1..R=9, S=1..Z=8 — equivalent to summing letter positions and reducing to a single digit. Each system can produce a different number for the same word, so the method must always be cited.
Academically, gematria is studied as a hermeneutic device — a tool for textual exegesis in Jewish and early Christian sources, not a predictive system. Popular numerology and modern "decoders" often blur this line by claiming the numbers reveal hidden meaning in arbitrary words or names. This calculator is a study tool: use it to explore how a verse, name, or term scores in each system, but treat any spiritual or predictive claim with appropriate skepticism. The numbers themselves are arithmetic; the meanings people attach are interpretive.
Educational and study tool. Gematria values are arithmetic facts; any spiritual, mystical, or predictive meaning is interpretive and depends on the tradition cited. Not a substitute for scholarly textual analysis.
