Writing Korean numbers
This converter writes South Korean Sino-Korean cardinals in Hangul: 23 is 이십삼 and 100 is 백. It uses 영 for zero. Native Korean words such as 하나, 둘 and 셋 belong to a different number system; they are explained in selected comparisons, not used as another converter mode.
Read four-digit groups with 만 (10000), 억 (100000000) and 조 (1000000000000). Join the syllables within a group and put a space between nonzero major groups: 12345 is 만 이천삼백사십오. Empty positions add no zero word.
One is omitted before 십, 백 and 천. This selected ordinary convention also uses 만 for 10000, but retains 일 in 일억 and 일조. Financial-style explicit-one wording, counters, currency, dates and times are outside this standalone tool.
Each clean number page has exact construction, a shared learning card and two-way practice. Practice checks Sino-Korean Hangul and the displayed group spacing; native Korean or romanized answers are not alternate spellings. Full-width digits work in numeric answers.
