How to calculate Greek gematria
Greek gematria (isopsephy) adds up the number each Greek letter stands for. Alpha
through theta count 1 to 9, iota through koppa count 10 to 90, and rho through sampi count 100 to
900. For λόγος ("word"): λ 30 + ο 70 + γ 3 + ο 70 + ς 200 = 373. Accents and
breathing marks add nothing, and final ς has the same value as σ.
Beta Code key: typing Greek on an English keyboard
The calculator reads Latin letters as Beta Code automatically. Watch for the letters that do not
match their look-alike: in Beta Code, h is eta, not a rough breathing, and q
is theta. Typing *)ihsou=s or simply ihsous gives Ἰησοῦς = 888.
Isopsephy is the Greek-language counterpart to Hebrew gematria: every letter of the Greek alphabet doubles as a number. The 24 standard letters run α=1 through ω=800 in ones, tens, and hundreds groupings, and three archaic letters no longer used in writing (digamma=6, qoppa=90, and sampi=900) fill the remaining gaps so every value from 1 to 900 is represented. Isopsephy predates Hebrew gematria in the written record and was used extensively in Greek magical, philosophical, and early Christian texts (most famously in debates over the numerical value of names in the Book of Revelation).
Greek Beta Code
Beta Code is a decades-old standard for representing the Greek alphabet using plain ASCII Latin letters, developed for the Thesaurus Linguae Graecae so Greek texts could be typed and stored on computers with no Greek character support. Most letters map to their obvious Latin look-alike (a=α, b=β, g=γ, d=δ), but a few do not: q=θ, c=ξ, h=η, f=φ, x=χ, y=ψ, w=ω, and v=ϝ (digamma). Accent and breathing marks such as ) ( / \ = | + are ignored. This calculator transliterates Beta Code to Greek and values it with standard Isopsephy, so you can calculate Greek gematria without switching keyboards.
Frequently asked questions
What is isopsephy?
Isopsephy is the Greek-language practice of calculating the numerical value of words and phrases using the Greek alphabet, where every letter also functions as a number. It is the direct Greek counterpart to Hebrew gematria and is historically older in the written record.
What is the most famous isopsephy calculation?
The number 666 ("the number of the beast") from the Book of Revelation is the most widely discussed isopsephy value in history, with centuries of scholarly debate over which name or title it was originally meant to encode. Another widely cited example is Ἰησοῦς (Iēsous, Jesus) = 888.
What is Beta Code and why would I use it?
Beta Code is a standard way of typing Greek with ordinary ASCII characters, created for the Thesaurus Linguae Graecae before computers could display Greek. Most letters match their Latin look-alike, but a few do not: q is θ, c is ξ, h is η, w is ω. Type "logos" and you get λογος = 373, the same as typing the Greek directly.
Is a "Greek beta gematria calculator" different from isopsephy?
No. People searching for a Greek beta or Beta Code gematria calculator want to enter Greek words with Latin keys. Beta Code only changes how you type the letters, not their values, so the result is always the standard isopsephy total. Both are calculated live in the tool above.
Do accents and breathing marks change the value?
No. Isopsephy values only the base letters. You can paste fully accented (polytonic) text from an edition such as the SBL Greek New Testament, and marks like ἰ, ῦ, or iota subscript are stripped before calculating, so Ἰησοῦς and ιησους both give 888.
