About Korean numbers
Korean uses two number systems: native Korean (하나, 둘, 셋… / counter forms 한, 두, 세…) and Sino-Korean (일, 이, 삼…). Mixing them is one of the most common beginner mistakes. This free tool drills the forms you need in real life — people, time, money, phone digits, floors, and more.
Time
Hours use native + 시 (한 시, 두 시). Minutes use Sino + 분 (십오 분). Combined: 세 시 십오 분.
Phone numbers
Read digit by digit with Sino-Korean. Zero is often 공 (or 영).
Money (원)
Prices always use Sino-Korean + 원 with place values 십, 백, 천, 만 (삼천 원, 만 원).
Age (살)
Everyday age uses native forms with 살: 한 살, 스무 살, 스물다섯 살. Practice contractions carefully for 1–4 and 20.
Objects, floors, duration
Objects: native + 개. Floors: Sino + 층. Months duration: Sino + 개월. Days duration: Sino + 일.
Tip: the unit (명, 시, 분…) is optional when you check — build the number first, then add the counter when you are ready.
