100 In Roman Numerals

100 in Roman numerals is C. Roman numerals are an ancient way of writing numbers, using letters from the English alphabet (in capitals). Each letter stands for a fixed value. For example, I = 1, V = 5, X = 10, L = 50, and C = 100. So, the number 100 is always shown as C in Roman numerals. No other letter can be used to replace it.
