Greek Gematria

The Greek Gematria Calculator (also called the Isopsephy Calculator) converts any Greek word, phrase, or sentence into its numerical value using the ancient Greek letter-number system. This system, known as isopsephy, was used by ancient Greeks and early Christians to find hidden meanings in names and texts through numerical analysis. Each letter of the Greek alphabet is assigned a specific number from 1 to 900, and the gematria value of a word is the sum of its letters' values.

The calculation follows the standard isopsephy mapping: α=1, β=2, γ=3, δ=4, ε=5, ϛ=6, ζ=7, η=8, θ=9, ι=10, κ=20, λ=30, μ=40, ν=50, ξ=60, ο=70, π=80, ϙ/ϟ=90, ρ=100, σ/ς=200, τ=300, υ=400, φ=500, χ=600, ψ=700, ω=800, ϡ=900. The calculator supports both lowercase and uppercase Greek letters, and properly handles special final-sigma (ς) and variant letter forms (koppa ϟ, sampi ϡ, stigma ϛ). Simply type or paste Greek text and click Calculate to get the isopsephy value instantly.

For example, the Greek word λογος (logos, meaning "word" or "reason") evaluates to 373: λ(30) + ο(70) + γ(3) + ο(70) + ς(200) = 373. The name Ιησους (Jesus) famously evaluates to 888: Ι(10) + η(8) + σ(200) + ο(70) + υ(400) + ς(200) = 888. The number 666, known as the "number of the beast" from the Book of Revelation, corresponds to the Greek spelling of several names depending on the manuscript tradition.

Regional Notes

Greek gematria (isopsephy) is a universal system rooted in ancient Greek and Hellenistic culture. It has no regional variations — the letter-value mappings are consistent across all Greek manuscripts from antiquity through the Byzantine period. Scholars in India, the US, the UK, and worldwide use the same standard isopsephy table for biblical studies, classical philology, and numerological analysis. The calculator defaults to the universally accepted Greek gematria values used by academic researchers internationally.
