How to Convert a Number to Words

Writing large numbers in word form can initially seem daunting, but with a few guidelines and a systematic approach, it becomes a manageable task. Follow along to see how to write out numbers using words.

To effectively write large numbers in words, it is essential to understand place values. Place values help in breaking down numbers into smaller, manageable parts. The following table shows the place values for numbers up to the trillion:

  • Hundreds: (100-999)
  • Thousands: (1,000-999,999)
  • Millions: (1,000,000-999,999,999)
  • Billions: (1,000,000,000-999,999,999,999)
  • Trillions: (1,000,000,000,000-999,999,999,999,999)

Each segment of a large number can be broken down into these categories, making it easier to convert into words.

Use the following steps to translate a number into word form:

Step One: Break Down the Number

Start by dividing the number into smaller groups of three digits, starting from the right. For example, the number 1234567890 can be broken into 1,234,567,890.

Each group (billions, millions, thousands, and ones) will be handled separately.

Step Two: Write Each Group in Words

Translate each group of three digits into words starting from the right. The first segment on the right is the hundreds value. For instance, the number 890 can be written as eight hundred and ninety.

Continue doing this for each group, moving from right to left and advancing the group as you go.

So, for the second group 567 in the example number above, write it out using thousands instead of hundreds, e.g. five hundred and sixty-seven thousand.

Step Three: Combine the Groups

Now, combine all the groups, ensuring you maintain their correct place values. Since we worked from right to left, be sure to reverse the resulting number to get the groups in the correct order.

Putting it all together, the number 1,234,567,890 from the example above in words is: one billion, two hundred and thirty-four million, five hundred and sixty-seven thousand, eight hundred and ninety.

Additional Tips

  • Hyphens: Use hyphens for numbers between twenty-one (21) and ninety-nine (99).
  • Consistency: Be consistent with your style. If you start using the word “and,” continue using it in the same way for each group in the entire number.
  • Complex Numbers: For very large or complex numbers, consider writing them in a more readable format. For example, 1,000,000,000,000 can be written as “one trillion” instead of “one thousand billion.”
