The chart covers three methods. Isopsephy is the standard Greek value, alpha 1 to omega 800. Ordinal counts each letter by position, 1 to 24. Reduced folds each value to a single digit. Three old letters served as numerals only: digamma (6), koppa (90), and sampi (900).
To find a word's value, read each letter and add the numbers, or use the Greek gematria calculator to do it instantly.
Frequently asked questions
What is the value of each Greek letter?
In isopsephy, the standard Greek method, alpha is 1, iota is 10, rho is 100, on up to omega at 800. The chart above lists every letter with its Ordinal and Reduced values too.
Why do some numbers have no Greek letter?
The 24 classical letters skip 6, 90 and 900. Three old letters once filled those gaps as numerals: digamma (6), koppa (90) and sampi (900).
How do I work out a Greek word from the chart?
Read each letter from the chart and add the numbers. For λόγος: lambda 30 + omicron 70 + gamma 3 + omicron 70 + sigma 200 = 373. Or type the word into the calculator and it adds them for you.
