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 in phone numbers.
Money (원)
Prices use Sino-Korean + 원 with place values 십, 백, 천, 만 (삼천 원, 만 원).
Age (살)
Everyday age commonly uses native forms with 살: 한 살, 스무 살, 스물다섯 살. Practice the special counter forms for 1–4 and 20.
Objects and durations
General objects commonly use native + 개. Floors use Sino + 층. For durations, 개월 and 일 are useful Sino-Korean patterns, while everyday Korean also has forms such as 한 달, 하루, and 이틀.
Pick the scenario you actually need and practice that number system with its counter instead of memorizing one giant rule table.
