Roman Numerals Converter: Tool to convert from / to Roman numerals.

Roman numeration is an additive numbering system used by ancient Romans. Roman numerals are represented using symbols combined with each other, in particular by the signs I, V, X, L, C, D and M, respectively representing the numbers 1, 5, 10, 50, 100, 500 and 1 000. These "abbreviations intended to notify and remember the numbers" did not allow their users to make calculations, which were carried out by means of abacuses. A number written in Roman numerals is read from left to right. As a first approximation, its value is determined by adding the individual values of each symbol, except when one of the symbols precedes a higher value symbol; in this case, we subtract the value of the first symbol from the second.

To convert a Roman numeral and find its value, it is necessary to know that a symbol which follows a symbol of a greater or equal value is added to the value of this one (eg "VI" is worth 5 + 1 = 6) , while if it precedes a symbol of higher value it subtracts from the value of the latter (thus "IV" is worth 5-1 = 4). As each letter can only be repeated three or four times in a row (depending on the method used), this limits the enumeration possibilities to respectively 3999 or 4999. Beyond that, by putting a horizontal bar above the letters, we multiply their number. value per 1000 (so-called vinculum system).
