Korean Numbers Explained! (2026 Ultimate Guide)

This is the 2026 Ultimate Guide to Korean Numbers.

About 10 years ago, I made a video on Korean numbers and it blew up.

And to this day, I still get comments.
I still get questions.
And I still see learners freeze in real life over the exact same thing.

“오… 다섯… wait, which one is it?”

So I started paying closer attention.
Not just to the rules, but to where people actually get stuck.

Over time, I found a way to explain this that feels a lot more intuitive.

That’s what this video is.

In this guide, I’m not just telling you “Sino Korean vs Native Korean.”

I’m giving you a rule that actually helps you choose.
❄️ Cold numbers mean you are reading a label. These are fixed, measured, or data based.
🤲 Warm numbers mean you are counting things you can actually see and interact with.

If you understand this one idea,
a huge part of Korean numbers starts to make sense.

In this video, we go through

• real life examples, not just textbook rules
• why it is 두 시 not 이 시
• when to use 개월 vs 달
• and the 100 rule that simplifies everything

Quick note.
If you are still working on how to read numbers like 하나, 둘, 셋, 넷,
go check out my beginner video first.

In this video, we are focusing less on repetition
and more on understanding how it actually works,
with lots of real examples.

If you want to go beyond understanding and actually start speaking Korean

👉 I run a group class where we learn through Korean culture
so the language actually sticks

👉 And a monthly subscription club where we study through K shows
with personalized feedback on your speaking and writing

Links are below.

Your turn!
Tell me something you would buy in Korea
and write the quantity using today’s rule. I will check it.
