How to Convert Numbers to Roman Numerals?

Converting numbers to Roman numerals is simple. Follow these steps:

Step 1: Break Down The Number

First, break the number into parts. For example, take the number 1987:

• 1000 + 900 + 80 + 7

Step 2: Convert Each Part

Next, convert each part to Roman numerals:

• 1000 = M
• 900 = CM
• 80 = LXXX
• 7 = VII

Step 3: Combine The Roman Numerals

Finally, combine all parts:

1987 = M + CM + LXXX + VII = MCMLXXXVII

Common Roman Numerals

Here are some common Roman numerals and their decimal values:

Roman Numeral	Decimal Value
I	1
II	2
III	3
IV	4
V	5
VI	6
VII	7
VIII	8
IX	9
X	10
XX	20
XXX	30
XL	40
L	50
C	100
D	500
M	1000

Rules for Writing Roman Numerals

There are rules for writing Roman numerals. Knowing these rules helps avoid mistakes.

Rule 1: No More Than Three In A Row

You cannot write the same numeral more than three times. For example, 4 is not IIII. It is IV.

Rule 2: Subtraction

Sometimes, you subtract a smaller numeral. For example, IX means 10 - 1. This equals 9.

Rule 3: Add When Larger

When a larger numeral comes first, you add. For example, VI equals 5 + 1. This equals 6.

Examples of Converting Numbers

Let's look at more examples:

Example 1: Convert 44

• 44 = 40 + 4
• 40 = XL
• 4 = IV

So, 44 = XLIV.

Example 2: Convert 99

• 99 = 90 + 9
• 90 = XC
• 9 = IX

So, 99 = XCIX.

Example 3: Convert 2023

• 2023 = 2000 + 20 + 3
• 2000 = MM
• 20 = XX
• 3 = III

So, 2023 = MMXXIII.
