# Number to Roman Numerals Online Converter

To convert a number to Roman numerals, you can use the following set of rules:

1. Roman numerals use the symbols I, V, X, L, C, D, and M to represent the numbers 1, 5, 10, 50, 100, 500, and 1,000 respectively.

2. To form a number, you can combine these symbols together. For example, the number 3 is represented as "III" (three ones), and the number 4 is represented as "IV" (one before five).

3. When a smaller numeral is placed before a larger one, it indicates subtraction. For example, the number 9 is represented as "IX" (one before ten).

4. When a numeral is repeated, it indicates addition. For example, the number 11 is represented as "XI" (ten and one).

5. When a numeral is repeated more than three times, it is usually replaced by a larger numeral. For example, the number 4 is represented as "IV" (one before five) rather than "IIII".

6. When a numeral is repeated more than 3 times it is usually replaced by a new numeral which is the next higher numeral of the same series with a smaller numeral added before it. For example, the number 4 is represented as "IV" (one before five) rather than "IIII".

It is important to keep in mind that there are no standard rules for writing Roman numerals, and different conventions were used in different periods and regions.
