Number to Words
Convert
Type a number and the tool returns it as words in your chosen language. Supports very large integers (uses BigInt internally) and decimal values up to your needs. English uses 'one thousand two hundred thirty-four' style with optional capitalization. Korean uses the Sino-Korean system with 만 / 억 / 조 grouping. Japanese uses 万 / 億 / 兆. Useful for filling out cheques, contracts, or writing clearer prose without lots of digits.
one million two hundred thirty-four thousand five hundred sixty-seven
Tip: decimals are spelled digit-by-digit after the decimal point.
How to use
- Type a number (digits, decimal point, optional minus sign).
- Pick the language (English / Korean / Japanese).
- Tap an example chip to try a sample.
- Copy the spelled-out text.
Frequently asked questions
- How big can the number be?
- Integer part uses BigInt, so practically unlimited. English supports up to quadrillion; Korean / Japanese support up to 京 (10^16), more than enough for currency or scientific use.
- How are decimals spelled?
- English: 'three point one four'. Korean: '삼 점 일사'. Japanese: '三点一四'. Each digit after the decimal is read individually.
- Does Korean use native or Sino-Korean numbers?
- Sino-Korean (일, 이, 삼, …), which is the system used for prices, dates, and most formal contexts. Native Korean (하나, 둘, 셋) is for counting objects and ages and isn't generated here.
- Is the output ready for a cheque?
- Close — most cheques want 'Twenty-five and 00/100' style with currency words. Use this output as a starting point and add the currency / cents phrasing manually.
