Greek gematria systems, explained
Isopsephy (Standard Greek)
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 (a=α, b=β, g=γ, d=δ, and so on), originally developed so Greek texts could be typed and stored on early computer systems that had no Greek character support. This calculator accepts Beta Code input, transliterates it to Greek, and then values it using standard Isopsephy — letting you 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.
What is Beta Code and why would I use it?
Beta Code is a standard way of typing Greek letters using ordinary ASCII/Latin characters (a=α, b=β, th=θ, and so on), created for early computer systems without Greek character support. Our Beta Code calculator lets you type Greek words on a regular keyboard and still get an accurate isopsephy value.
