Number to Korean
Converts a number into formal Korean money words — 350,000 becomes 일금 삼십오만 원정, the notation Korean contracts, receipts and official documents require alongside the digits. Type the amount, copy the phrase.
How to use
- Enter the amount in digits.
- Read the formal Korean rendering, wrapped in the standard 일금 … 원정 frame.
- Copy it into the contract or receipt next to the numerals.
- Double-check large amounts digit by digit — the point of the exercise is that the two forms must agree.
When you actually need this
- Filling the Korean-words amount line on a contract or loan agreement.
- Writing formal receipts and invoices that show the sum in words.
- Preparing congratulatory or condolence envelopes with amounts in formal style.
- Learning how Korean groups large numbers — by ten-thousands, not thousands.
Why the words, and why ten-thousands
Amounts in words resist the classic fraud of adding a digit to numerals — 일금 ("the sum of") seals the front and 원정 ("won exactly") seals the back, so nothing can be appended at either end. The system groups by 만 (10⁴): 억 is 10⁸ and 조 is 10¹², which is why 350,000 reads as thirty-five man rather than three-hundred-fifty thousand — the perennial stumbling block between Korean and Western numbering. Formal financial documents often use anti-tamper numerals (壹, 貳, 參) in place of the plain ones; this tool produces the standard Hangul form used in everyday contracts.

FAQ
How does Number to Korean count characters with spaces and emoji?
It reports both a count with spaces and one without, so you can match whichever rule your form uses. Emoji and other characters outside the basic range are counted as a single visible character rather than as the two code units JavaScript stores internally.
Does Number to Korean work for languages other than English?
Yes. Korean, Japanese, Chinese, Hindi, Arabic and accented European text are all handled correctly. Word counting splits on whitespace, so for Chinese and Japanese the character count is the more meaningful figure.
Is my text saved anywhere?
No. Everything runs in the page itself and nothing is transmitted or stored — you can paste a draft, a contract or private notes without it leaving your device.
