How to convert pyeong to square meters
The pyeong (평) is the old Korean unit for floor area. One pyeong is exactly 400/121 square meters, about 3.3058 m² — a square of about 1.82 m × 1.82 m.
Formula: m² = pyeong × 3.305785
Example: 25 평 × 3.305785 = 82.64 m²
The other way is even easier, because 121/400 is a short number: one square meter is exactly 0.3025 pyeong.
Formula: pyeong = m² × 0.3025
Example: 84 m² × 0.3025 = 25.41 평
Features
- Instant answer — type pyeong in the From box and see square meters as you type
- Exact factor — 1 평 = 400/121 m², not a rounded 3.3, so big sizes stay right
- Swap (⇄) — turn m² into pyeong in one click, with no rounding error
- Tsubo too — the Japanese tsubo (坪) is in the same list; it is the same size
- Bulk convert a list — paste many sizes, one per line or a column from Excel; each line keeps its place
- Three ways to show the list — Results only, Value and result or CSV (for Excel), with 0 to 6 Decimal places

Square meters to pyeong: apartment sizes
Korean apartments are listed by their exclusive area in m². Here is each common size in pyeong. Because 1 m² is exactly 0.3025 평, these numbers are exact.
| Exclusive area (m²) | Pyeong (평) |
|---|---|
| 39 | 11.7975 |
| 49 | 14.8225 |
| 59 | 17.8475 |
| 74 | 22.385 |
| 84 | 25.41 |
| 101 | 30.5525 |
| 114 | 34.485 |
| 135 | 40.8375 |
Why a "25평 apartment" has only 59 m²
Korean flats have two sizes, and the pyeong name usually comes from the bigger one:
- 전용면적 (exclusive area) — the space inside your front door: rooms, kitchen, bathrooms
- 공급면적 (supply area) — the exclusive area plus your share of the hall, stairs and lift
So a 59 m² flat has 17.85 평 inside, but people often call it a "24평" or "25평" flat, because its supply area is about 80 m². An 84 m² flat (25.41 평 inside) is usually called "33평" or "34평", with a supply area of about 110 m². The balcony is not in either number, which is why a flat can feel bigger than its m².
Since 2007, ads and contracts in Korea must use square meters, but people still talk in pyeong every day.
Where the number comes from
A pyeong is a square of 6 × 6 ja (자), the old Korean foot. One side is 1 kan (칸) = 20/11 m ≈ 1.818 m, so one pyeong = (20/11)² = 400/121 m². It came from the Japanese tsubo (坪), which is the same size. Taiwan uses the same unit too, called ping (坪).
Pyeong in daily life
- A studio (원룸): 20 m² = 6.05 평
- A café: 30 평 = 99.17 m²
- A big family flat: 135 m² = 40.84 평
- A quick guess: pyeong × 3.3 = m², and m² ÷ 3.3 = pyeong (exact: × 0.3025)
