Greek numerals basics
Greek numerals are commonly written using the Ionian or Milesian system, where Greek letters represent values for ones, tens, and hundreds. Instead of separate numeral symbols, the value is created by combining the right letters in order, then marking them as numerals.
A keraia mark (ʹ or ʹ) is typically used to show that letters are being used as numbers, and a thousands mark (͵) is used for values in the thousands. This Greek numerals converter follows these conventions so results are easy to read and copy into documents.
For example, 3333 can be written as ͵γτλγʹ in Greek numerals.

Conversion rules
Greek numerals are usually written by combining hundreds, tens, and ones in order, then adding the keraia mark (ʹ or ʹ). For thousands, the thousands mark (͵) is placed before the letter that represents the thousands value.
If you see different styles online, it is often due to font differences or alternate marks, but the underlying values are the same.
Examples
- 1 = αʹ
- 9 = θʹ
- 10 = ιʹ
- 24 = κδʹ
- 99 = ϟθʹ
- 3333 = ͵γτλγʹ
