Frequently asked questions
- What happens with numbers ending in 11, 12, or 13?
- They always get "th", 11th, 12th, 13th, 111th, 212th, even though they end in 1, 2, or 3. The tool handles this exception automatically, so you don't have to remember the rule.
- Does it work with negative numbers or zero?
- Zero converts to 0th, and negative numbers work too (-3 becomes -3rd), which is handy for labeling ranks, offsets, or sequence positions that can dip below zero.
- Can I convert a whole list at once?
- Yes. Paste multiple numbers separated by spaces, commas, or line breaks and it converts every one in a single pass instead of doing them one at a time.
