How to convert Arabic to Roman?

Converting Arabic numerals to Roman numerals might sound like a task straight out of an ancient scroll, but it’s actually pretty straightforward once you get the hang of it! Here’s the lowdown on the theory and rules to make you feel like a Roman numerals pro in no time.

The Basics

The Roman numeral system is based on combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M. Each letter represents a specific value, and when combined, they form different numbers. Here’s your cheat sheet for singular Roman numerals and their Arabic equivalents:

  • I = 1
  • V = 5
  • X = 10
  • L = 50
  • C = 100
  • D = 500
  • M = 1000

The Rules

  1. Repeat to Accumulate: You can repeat a numeral up to three times to add up values. For example, III is 3.
  2. Larger Before Smaller Adds: If a smaller numeral follows a larger one, you add them. For example, VI is 5 + 1 = 6.
  3. Smaller Before Larger Subtracts: If a smaller numeral comes before a larger one, you subtract the smaller from the larger. For example, IV is 5 – 1 = 4.
  4. Limited Use: The numerals V, L, and D can only be used once and not repeated like I, X, C, and M. So, you can have V (5) but not VV (10).

Example: Converting 34 to Roman Numerals

Let’s take a look at a simple example: the number 34. Here’s how you break it down:

  • 30 is written as XXX (10 + 10 + 10).
  • 4 is written as IV (5 – 1).

So, when you put it together, 34 in Roman numerals is XXXIV.

Now you’re all set to impress your friends with your newfound ability to convert Arabic numerals to Roman numerals. Remember, with great power comes great responsibility – don’t go labeling everything in sight with Roman numerals.

Handling Number Bigger Than 4000

In the Roman numeral system, once you hit 4000, you need to introduce a horizontal line above the numbers. This line isn’t just for show – it means that the number should be multiplied by 1000.

For example, if you want to write 5000, you don’t just write a plain old V. Instead, you add a stylish horizontal bar above the V, transforming it into 5000. Think of it as Roman numerals getting a bit of a fashion upgrade!


  • 5000: Instead of V, you write (that’s V with a bar on top).
  • 4000: Instead of IV, you write I̅V̅ (IV with bars on top, indicating 1000 times the value).

This little trick allows Roman numerals to stretch into the thousands without having to string together a bunch of Ms and look like alphabet soup.

So, let’s say you wanted to write 6000. You’d take 5000 (V̅) and add 1000 (M), giving you V̅M. It’s like a secret code, but once you know the rules, you’re all set to impress with your ancient numeral knowledge!

Now you can navigate the world of Roman numerals beyond 3999 with confidence. Whether you’re planning a historical reenactment or just trying to be the coolest person at the trivia night, you’ve got the knowledge to handle those big numbers like a true Roman scholar!
