Korean Number Converter
About this tool
Numbers are read in groups of four digits (만, 억, 조, 경). 1,234,500 becomes 백이십삼만 사천오백원 in Korean, 일금 일백이십삼만사천오백원정 in contract style, 金 壹佰貳拾參萬肆仟伍佰圓整 in formal Hanja, and 123만 4,500원 with digits and units.
Contract style writes every 1 (일백, 일십) with no spaces so the amount is hard to alter; formal Hanja numerals (壹 貳 參) add strokes to 一 二 三 for the same reason.
BigInt keeps up to 20 digits exact.
