Click on "Input Number", then type a number between 0 and 3999 with no decimals. You will then be given the roman numeral version of that number, which you may copy and paste. Click on -1 to subtract from the current translation, or +1 to add to it. This engine uses standard roman numerals (ⅠⅤⅩⅬⅭⅮⅯ) and does not support decimals.
Fun fact! Roman numerals can be written in many ways. This engine uses standard, but the complicated math behind roman numerals allows for some very interesting combinations. A few fun examples: ⅦⅩ = 3 ⅠⅬⅭ = 96 ⅬⅠⅭ = 94 ⅢⅤⅩ = 8 ⅩⅥⅩ =14 ⅩⅥⅩⅩ = 4 ⅭⅭⅩⅯⅠⅭⅤ = 844 I encourage you to try to find complicated combinations yourself! It's a very fun brainteaser.
