Number to Words

Convert numbers into words (e.g., 145 → one hundred forty-five).

How to Do It Manually

To convert a number to words, break it into groups of three digits (thousands, millions, billions, etc.) and convert each group.

  1. Split the number into groups of three from the right (ones, thousands, millions…).
  2. Convert each three-digit group: hundreds place, then tens and ones (using special words for 11–19).
  3. Append the group name (thousand, million, billion) where appropriate.
  4. Join all groups with spaces.
