Frequently asked questions
How big a number can it convert?
Up to 10^15 (quadrillion). Beyond that, scientific notation makes more sense than spelling out.

Currency conventions?
USD (dollars/cents), GBP (pounds/pence), EUR (euros/cents), and custom (set your own unit names). Decimal handled per locale.
Does it match Indian numbering (lakhs, crores)?
Yes — toggle "Indian English" or "Indian Hindi" for the lakh / crore conventions.
Privacy?
All conversion in browser.
Pro tips
- For cheques, always cross-check the words version against the digit version. Words win if they disagree.
- For legal contracts, include both forms in parentheses: "fifteen thousand dollars ($15,000)" — banking standard.
- For currency, decide your decimal handling explicitly: "and 50/100" (cheque style) vs "and fifty cents" (formal prose).
- For Indian audiences, the lakh / crore conventions matter — "fifteen lakh" not "1.5 million".
