Roman numerals: common questions
How do you read Roman numerals?
Add the symbols from left to right, except when a smaller one comes before a larger one, which is subtracted: IV = 4, IX = 9, XL = 40, XC = 90, CD = 400 and CM = 900. I, X, C and M repeat at most three times; V, L and D never do.
Why does it stop at 3999?
Because the modern form only uses I, V, X, L, C, D and M, and 4000 would need four Ms or a bar on top, which has no common standard. Forms such as IIII or VX are rejected because they are not standard.
Is there a zero in Roman numerals?
No. The Romans had no symbol for zero, so the tool converts from 1 to 3999.
Is my text sent to a server?
No. Everything is calculated in your browser as you type; the text is not sent to Cocuyo or any third party and is not stored. You can check it in your browser’s network tools: your file is not sent.
