What is this tool?

Sometimes you need to convert decimal values into their Roman numeral character representations.

While many of us know small decimal numbers in Roman numeral form such as 5 being "V" or 6 being "VI", larger numbers such as 6645 (MMMMMMDCXLV) are very tricky to get right in your head.

To use this tool enter your numbers into the left box, click "convert" and their Roman numeral equivilant will be shown on the right.

To convert multiple numbers they have to be separated by a space, newline or both; the tool automatically detects this.
