Korean Numbers | How to Count in Korean

How to Count 1-10 in Korean

Let’s first take a look at the 1-10 in Sino-Korean.

1—일 il
2—이 i
3—삼 sam
4—사 sa
5—오 o
6—육 yuk
7—칠 chil
8—팔 pal
9—구 gu
10—십 sip

Korean Numbers 11-99

The general rule to form a double-digit number is number + 십(sip) + number, reading the numeral from left to right:

24 = 이십사 (two-ten-four)
92 = 구십이 (nine-ten-two)

For numbers 11-19, it’s just 십(sip) + number:

11 = 십일 (ten-one)
16 = 십육 (ten-six)

If the number is the multiples of 10, it’s number + 십(sip):

30 = 삼십 (three-ten)
90 = 구십 (nine-ten)

Important note: the rules for 10-99 will be used again if you encounter them in larger numbers above 100.

Now let’s enjoy a song of Sino-Korean numbers!

What’s Hundred, Thousand and Ten Thousand in Korean?

The number units 백(baek), 천(cheon), and 만(man) can be used directly for 100, 1000 and 10,000:

100 = 백 (baek) means “hundred”
1000 = 천(cheon) means “thousand”
10,000 = 만(man) means “ten thousand”

Counting 100~999 in Korean

To form any number between 100~999, the general rule is number + 백 + number+ 십 + number, reading the numeral from left to right:

If the number is 100~199, start with 백 directly:

113 = 백십삼 (hundred-ten-three)
189 = 백팔십구 (hundred-eight-ten-nine_

Counting 1000~9999 in Korean

To form a four-digit number, the general rule is number + 천 + number + 백 + number + 십 + number, reading the numeral from left to right. For example:

If the number is 1000~1999, start with 천 directly:

1199 = 천백구십구 (thousand-hundred-nine-ten-nine)
1812 = 천팔백십이 (thousand-eight-hundred-ten-two)

Counting in Korean vs Counting in English

만(man) is an important word in Sino-Korean numbers because the Korean number system uses increments of 10,000 rather than 1,000.

For example,

10,000 — 만(man) — ten thousand
1,000,000 —”백만(baekman) — million
10,000,000 — “천만(cheonman) — ten million
100,000,000 — 억(eok) — billion

(which turns into the new increment for the numbers over this one)

Why Do Koreans Use Two Systems for Counting?

Before King Sejong created Hangul in 1443, Koreans had to use Chinese characters for writing, and many Korean words, such as numbers, were influenced by the Chinese language. After Hangul was born, Koreans have developed two number systems with distinct usage over the years.

When to Use Which Korean Number System

Native Korean numbers are used for quantifying items, expressing age, the hour or counting months. On the other hand, Sino-Korean numbers are used in more specific cases, such as dates, telephone numbers, addresses, and counting days or money.

Sino-Korean Numbers with Hanja Counters

Sino-Korean numbers are known to have inseparable friendship with some Hanja counters. “Hanja” means that these count words originated from the Chinese language. Here are some common Hanja counters that are used after a Sino-Korean number: 년(nyeon), 월 (wol), 일(il), 분(bun), 초(cho), 원(won), 주일(juil), 층(cheung), and 인분(inbun).

How to Count in Korean with Native-Korean Numbers

1 — 하나 hana
2 — 둘 dul
3 — 셋 set
4 — 넷 net
5 — 다섯 daseot
6 — 여섯 yeoseot
7 — 일곱 ilgop
8 — 여덟 yeodeol
9 — 아홉 ahop
10 — 열 yeol

Counting up to 99 with Native Korean Numbers

Unlike Sino-Korean numbers, the native Korean numbers have different names for each of the tens, and they are used to create any other number between 20 and 99.

20 — 스물 seumul
30 — 서른 seoleun
40 — 마흔 maheun
50 — 쉰 swin
60 — 예순 yesun
70 — 일흔 ilheun
80 — 여든 yeodeun
90 — 아흔 aheun

If you want to make a native Korean number from 11 to 19, the rule is: 열(ten) + number between 하나(one) and 아홉 (nine) inclusive. For example:

11 = 열하나 (ten-one)
18 = 열여덟 (ten-eight)

If you want to make native Korean numbers from 21 to 99 excluding multiples of tens, you need to combine a number for the tens and a number between 1 and 9 inclusive. For example, the tens number for 21~29 is 스물 (twenty). To make a number from 21 to 29, the rule is 스물(twenty) + number between 하나(one) and 아홉 (nine) inclusive. For example:

25 = 스물다섯 (twenty-five)
23 = 스물셋 (twenty-three)

Native Korean numbers from 31 to 99 are made in the same manner. Here are more examples of numbers from 31 to 99:

35 = 서른다섯 (thirty-five)
43 = 마흔셋 (forty-three)
58 = 쉰여덟 (fifty-eight)
66 = 예순여섯 (sixty-six)
71 = 일흔하나 (seventy-one)
89 = 여든아홉 (eighty-nine)
94 = 아흔넷 (ninety-four)

Counting above 100 with Native Korean numbers?

👉The maximum that the native Korean number can reach is 99. For any numbers starting from 100, the Sino-Korean number system is used.

Specify Quantities with Native Korean Numbers

The general usage is Noun + Number + Count word in a sentence.

Example:

사과 네 개가 있어요.

There are four apples.

Like Hanja counters with Sino-Korean numbers, native Korean numbers are also used with collocative count words to specify quantities of items.

The most common counter is 개(gae), which can be used in most situations when counting items. Here are some more examples: 개(gae), 달(dal), 시(si), 시간(sigan), 명(myeong), 살(sal) and 마리(mari).

Native Korean has five numbers that take a short form before a count word: 하나, 둘, 셋, 넷 and 스물. Here they are, followed by 살 (years old) as examples.

How to Use Korean Numbers in Real Life?

Asking Number-Related Questions with 몇 and 얼마

Use the question word 몇(myeot) when the answer involves counters such as 시 (time), 살 (years old), 명 (persons), etc.

Examples:

몇 살이에요?
How old are you?

내일 사람 몇 명 만나요?
How many people will you meet tomorrow?

내일 몇 시에 일어날 거예요?
What time are you going to get up tomorrow?

Use the question word 얼마 (eolma) when you ask for the amount, price and degree that you do not know exactly.

가격이 얼마예요?
How much is the price?

여기서 얼마나 멀어요?
How far is it from here?

How to Say Zero in Korean

There are two ways of saying zero in Korean: 영 (yeong) and 공 (gong).

영 is used in arithmetic:

0 X 1 = 0 → 영 곱하기 일은 영 (zero multiplied by one is zero)
0.35 = 영 점 삼오 (점 means dot)
0.0002 = 영 점 영영영이

공 is used for phone numbers or other occasions in which people say numbers digit-by-digit. The digit 0 is then pronounced as 공.

Example:

010 0101 1234 = 공일공 공일공일 일이삼사

Ask and Talk About Date and Time in Korean

You can ask the date of a day like this:

오늘 몇월 며칠이에요?

What’s today’s date?

Expressing the date in Korean is in year-month-day format,: from the biggest and down to the smallest unit. You can say 년(nyeon), 월(wol), and 일(il), (which is year, month, day respectively)after the numbers, as Sino-Korean numbers.

Example:

오늘은 7월(칠월) 12일(십이일)이에요.

It is July 12th today.

Korean months are named after their numeral sequences in a year with Sino-Korean numbers. They don’t have individual names in the same way as English.

The names are formed with the number + 월 (wol). Notice that the numbers in 유월 (June) and 시월 (October) undergo a form change.

Months in Korean
Sequence in year	English	Korean
1st	January	일월 ilwol
2nd	February	이월 iwol
3rd	March	삼월 samwol
4th	April	사월 sawol
5th	May	오월 owol
6th	June	유월 yuwol
7th	July	칠월 chilwol
8th	August	팔월 palwol
9th	September	구월 guwol
10th	October	시월 siwol
11th	November	십일월 sibilwol
12th	December	십이월 sibiwol

To ask the time, you can say:

지금 몇 시예요?

What time is it now?

When we tell the time in Korean, we use both Sino-Korean numbers and native Korean numbers.

We use native-Korean numbers in front of 시 for the hour, and Sino-Korean numbers in front of 분 for the minute.

3:15 = 세 시 십오 분
7:05 = 일곱 시 오 분

Ask and Talk About Prices in Korean Numbers

When you want to know the price for something, you can ask:

(이거) 얼마예요?

How much (is this)?

To say the price, you just add the money unit “won” after a Sino-Korean number. But you need to remember the Korean won comes in 만(man, 10000) increments, as the price increases.

For example:

500 won = 오백 원
9,000 won = 구천 원
12,000 won = 만이천 원
369,900 won = 삼십육만구천구백 원
5,000,800 won = 오백만팔백 원

Ask and Talk About House Numbers and Phone Numbers in Korean

When you ask about one’s address, you can say:

몇 동 몇 호에 사세요?

What is your house number?

동 is a unit for building number and 호 is for room number.

To answer, you can just add the count word after sino-Korean numbers.

백이 동 천일 호 = Building 102 Room 1001
사 동 오백이 호 = Building 4 Room 502

To ask the phone numbers, you can say:

전화번호가 어떻게 되세요?

What is your phone number?

To say a phone number, you just need to say it digit by digit as Sino-Korean numbers:

010-1234-5678 = 공일공 일이삼사 오육칠팔

Using Numbers When Ordering Items

When you order something, you just need to say the items and quantities, usually as native Korean numbers.

When ordering one item, you can omit the count words:

아이스아메리카노 하나 주세요.

Please give me one iced Americano.

아이스아메리카노 한 잔 주세요.

Please give me one glass of iced Americano.

You can use the most common count word 개 in most cases, even if you don’t know what the collocative count word for the item is.

공책 한 권 주세요 = 공책 한 개 주세요.

Please give me one notebook.
