Greek Gematria Calculator

Greek gematria, traditionally known as Isopsephy (from the Greek "ἰσοψηφία" meaning "equal pebbles"), is one of the oldest forms of alphabetic numerology in the Western world. The practice emerged from the ancient Greek numeral system, where letters served as numbers before the adoption of Arabic numerals. This dual function of letters created a natural connection between words and mathematics that Greek philosophers, mystics, and early Christians explored extensively.

Unlike Hebrew gematria which developed within Jewish mystical traditions, Greek Isopsephy flourished in the broader Hellenistic world, influencing religious thought, philosophy, and even political discourse throughout the Mediterranean. The practice was particularly significant in early Christianity, as the New Testament was originally written in Koine Greek. Early Church fathers analyzed biblical texts using Isopsephy to find hidden meanings and divine connections.

The most famous example of Greek gematria in the Bible is the "Number of the Beast" - 666 - found in Revelation 13:18. The verse explicitly instructs readers to "calculate the number," directly referencing the practice of Isopsephy. Scholars have long debated whether 666 refers to Emperor Nero (whose name equals 666 when transliterated into Hebrew) or carries purely symbolic meaning.

Today, Greek gematria remains valuable for scholars studying the New Testament, researchers exploring ancient numerology, and anyone interested in the numerical patterns that ancient Greeks found meaningful. Our calculator supports both Greek characters and English transliterations, making this ancient practice accessible to modern users.

The Greek numerical system assigns values to 27 symbols (24 standard letters plus 3 archaic letters). The pattern follows a logical structure: the first nine letters represent units (1-9), the next nine represent tens (10-90), and the final nine represent hundreds (100-900). This organization made the Greek alphabet function as both a writing system and a complete numerical notation.

This calculator accepts both Greek Unicode characters (like αβγδ) and English transliterations. When entering transliterated text, the calculator maps common romanizations to their Greek equivalents. For a complete reference of all letter values, consult our gematria chart.

Three archaic letters were retained specifically for their numerical values: Digamma (ϝ/Ϝ = 6), Koppa (ϟ/Ϙ = 90), and Sampi (ϡ/Ϡ = 900). While no longer used in writing, these letters were essential for expressing certain numbers in the Greek system.
