Roman Numerals are the ancient Roman way of representing numbers. Just like today as we have the modern numeral system, Romans had their own system of representing numbers.

The number system that we use all the time is Hindu-Arabic numerals. These are the set of 10 symbols – 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0. Also, it is inspired by Roman numerals. You can notice the similarity when you compare both systems side by side. However, Hindu-Arabic is a more efficient and convenient way of writing. Also, the Roman system has its own advantages too.
Let's take an example to understand the conversion process. For successfully converting a number into its equivalent Roman form you will need the Roman Numerals Chart. So, keep it handy or you can memorize it.
Firstly, let's break the number into Thousands, Hundreds, Tens, and Ones and do each conversion.
Now write all together:
1000 + 300 + 80 + 5 = M + CCC + LXXX + V
So, 1385 ➔ MCCCLXXXV
Try your own examples to get acquainted with this technique. However, the Roman Numerals Converter makes the job simple. Just enter the number and press the convert button. You will get the result in less than a second.
The process for converting a Roman symbol to an arabic number is the same. There are just a few small changes that you need to take care of. Let's understand this clearly with an example.
Firstly, let's break all the letters and write them down respectively. Then convert each letter into a number.
Now, sum up all the values: 10 + 10 + 5 + 1 = 26
Hence, the number form of XXVI is 26.
This was all about what are Roman Numerals and how you can change a number from one form to another form easily. Also, our converter is a great tool that you can use to achieve the same. Just access the website and start using it. No need to signup or register to get access.
