Greek Isopsephy Calculator – Greek Gematria Values

Isopsephy (ἰσοψηφία, “equal pebbles”) is the Greek counterpart of gematria. Paste Greek text with or without accents.

Greek letter values

The Greek alphabetic numerals kept three letters that had dropped out of writing: stigma/digamma (ϛ, ϝ) for 6, koppa (ϙ) for 90 and sampi (ϡ) for 900. With them the alphabet covers 1–9, 10–90 and 100–900.

Units	Tens	Hundreds
α = 1	ι = 10	ρ = 100
β = 2	κ = 20	σ = 200
γ = 3	λ = 30	τ = 300
δ = 4	μ = 40	υ = 400
ε = 5	ν = 50	φ = 500
ϛ = 6	ξ = 60	χ = 600
ζ = 7	ο = 70	ψ = 700
η = 8	π = 80	ω = 800
θ = 9	ϙ = 90	ϡ = 900

Accents, breathing marks and the iota subscript are ignored; capital and small letters count the same; final sigma (ς) is 200 like σ.

Ancient examples

Nero, 1005. Suetonius quotes a Greek lampoon, “A calculation new: Nero his mother slew” (Suetonius, Nero 39.2). The joke is that Νέρων = 1005 and ἰδίαν μητέρα ἀπέκτεινε (“he killed his own mother”) = 1005. Try both in the calculator.
Abraxas, 365. Irenaeus reports that the Basilidians named their chief power Abraxas “and, on this account, that word contains in itself the numbers amounting to three hundred and sixty-five” (Against Heresies 1.24.7). ΑΒΡΑΣΑΞ = 365.
Ἰησοῦς, 888. A Christian section of the Sibylline Oracles gives the name as a riddle, eight units, eight tens and eight hundreds (Sibylline Oracles 1.324–331). Ἰησοῦς = 888.
666 and 616. Irenaeus discusses the number in Revelation 13:18. He says it is reckoned “according to the Greek mode of calculation”, and that some copyists had reduced the middle figure by fifty (Against Heresies 5.30.1). The reduced figure is the reading 616. See 666.

Greek and Hebrew

The two systems work the same way but give different results for the same name, because the alphabets and values differ. Write a Hebrew name in Hebrew letters to get its gematria, and a Greek name in Greek letters to get its isopsephy.
