Roman numerals system is a numeral system where numbers are represented by combining Latin alphabet letters. The Roman numeral system was the standard way of writing numbers throughout Europe during the Middle Ages.

In this article, I am going to teach you how to easily convert from Arabic or English numerals to Roman numerals and vice versa using Microsoft Excel or Word.

Without any further ado, let’s get started.

Convert Roman numerals into numbers

Converting Roman numerals to numbers can be done easily with Excel. Whether you want to convert just one roman numeral or a huge list of them, Excel can help you with its Arabic function.

The ARABIC function converts Roman numerals to Arabic numerals. It was added in Excel 2013. Thus, this function will not work for you if you are using an older version of Excel prior to Excel 2013.

Without any further ado, below illustrates how you can convert roman numerals into numbers using the Arabic Excel function.

Syntax:

=ARABIC (roman_text)

Where: roman_text is the Roman numeral in text that you want to convert.

For example, the following formula converts xii to 12:

=ARABIC (“xii”)

Converting Roman Numerals to Arabic or English Numbers

You can also include references to another cell or cells in your formula. This enables your formula to work dynamically with the data contained in those cells you are referencing from.

For example, if your formula refers to cell A3 and you change the value contained in A3, the formula result changes to reflect the new value. If you don’t use references in your formulas, you would need to edit the formulas to be able to change the values.

The ROMAN function in Excel is used to convert Arabic numerals to roman numerals.

This function is explained below with examples.

Syntax

=ROMAN(number, [form])

Where: number is the Arabic number you want to convert into Roman numeral. The [form] part of the function is optional and is not even relevant here.

For example, the following formula converts 24 to XXIV:

=ROMAN(24)

Just like in the first example with the Arabic function, you can also include references to another cell in your formula. This enables your formula to work dynamically with the data contained in the cells you reference.

For example, if your formula refers to cell A3 and you change the value contained in A3, the formula result in cell B3 will also change to reflect the new value. If you don’t use references in your formula, you would have to edit the formula itself to be able to change the values.

Two curly braces (known as field characters) will appear. Type =Number\*ROMAN between the two curly braces and press F9 to convert the Arabic number to a Roman numeral.

For a more detailed steps to perform this task, obey the following instructions:

  • Between these curly braces, type the following code.
