Roman Number Conversion Calculator This calculator converts Roman numerals to Arabic numerals and vice versa. Roman numerals use the following numbers: I=1, V=5, X=10, L=50, C=100, D=500, and M=1000. Most of the time, they are just sorted and added. Exception: When a numeric character is to the left of a numeric character with a higher value, the smaller value needs to be subtracted.
