Two Ways Koreans Read Numbers
Phone numbers are read as 일, 이, 삼 (il, i, sam), but ages are read as 스물, 서른 (seumul, seoreun) — Korean uses two completely different number systems, and mixing them up is one of the most common mistakes learners make. This tool instantly converts any number you type into both the Sino-Korean (한자어) and Native Korean (고유어) reading.
Sino-Korean numbers are used for money, dates, phone numbers, and most counting above 99, automatically scaling up through 만, 억, and 조. Native Korean numbers are used for age, quantities, and time (한 시, 두 시), but traditionally only exist from 1 to 99 — so this tool limits that mode to keep results accurate.
Whether you're studying Korean, subtitling a video, or double-checking how to say a large number out loud, just type a number and pick a reading style to see the result immediately.
Frequently Asked Questions
Use Sino-Korean (일, 이, 삼) for money, dates, phone numbers, and order. Use Native Korean (하나, 둘, 셋) for age, quantity, and time.
No — traditional Native Korean numbers only go up to 99, so this tool restricts that mode to 1-99. Use Sino-Korean for larger numbers.
The converter is optimized for whole numbers, so any decimal portion is automatically dropped.
