This tool converts a numeric amount into the Korean '일금 …원정' wording used on contracts, receipts, and quotes. It automatically applies the 만/억/조 (ten-thousand/hundred-million/trillion) units when reading it out, and supports both the formal style (with '일' included, as in 일십/일백/일만) and a concise colloquial style.

How to use

  1. Enter the amount as a number. Commas (,) are ignored automatically.
  2. If needed, use the 'Formal style' checkbox to switch to the notation that includes '일'.
  3. The '일금 …원정' wording, the Korean reading, and the comma-formatted number all appear together.
  4. Click the copy button for the form you want and paste it into your document.

FAQ

Why write the amount in Korean words too?
Numbers alone are easy to tamper with—changing '1,000' to '10,000,' for instance—so contracts, checks, and receipts also spell out the amount in Korean ('일금 …원정') to lock it in. This tool generates that wording automatically.
What's the difference between the formal and colloquial styles?
The colloquial style reads 10,000 as '만,' while the formal style prefixes '일' throughout, as in '일만.' For example, 1,234,500 is '백이십삼만사천오백' colloquially and '일백이십삼만사천오백' formally. Choose to match your document's convention.
Can the notation vary by institution?
The Korean amount notation follows widely used conventions and is for reference. Some places write '원정' as '원整' or use formal Chinese numerals (壹, 貳, etc.), so if a specific format is required, check that institution's template. Decimals are ignored and only the whole-number amount is converted.
