Open Pyeong Calculator →What Is a Pyeong and How Does It Relate to m²?
Pyeong (평, 坪) is a traditional area unit still widely used in Korean real estate, inherited from the Japanese measurement system. The exact conversion is:
- 1 pyeong = 3.305785 m² (exactly 400/121 m²)
- 1 m² = approx. 0.3025 pyeong
The formulas are straightforward:
- Pyeong → m²: pyeong × 3.305785
- m² → Pyeong: m² × 0.3025
For example, 84 m² × 0.3025 = approx. 25.4 pyeong, and 32 pyeong × 3.305785 = approx. 105.8 m². Minor differences between calculators come from rounding; FreeSign uses the full coefficient 3.305785 for accuracy.
How to Convert — 2 Steps
- Enter the number — Go to the Pyeong Calculator and type the value you know — either pyeong or m².

Common Apartment Size Conversion Chart
Korean apartments are advertised in two different area figures — exclusive area (전용면적), which is the liveable floor space inside your unit (rooms, living room, kitchen, bathrooms), and supply area (분양·공급면적), which adds shared spaces like corridors, stairwells, and elevators. The "84㎡ apartment" you see in listings refers to the exclusive area; the supply area and pyeong count are larger. Always confirm which figure you are looking at before signing a contract.
| Supply Area (pyeong) | Converted m² (×3.305785) | Typical Exclusive Area Type |
|---|---|---|
| 17 pyeong | approx. 56.2 m² | Exclusive ~39 m² (small studio / officetel) |
| 24 pyeong | approx. 79.3 m² | Exclusive ~59 m² (2-person household) |
| 32 pyeong | approx. 105.8 m² | Exclusive ~84 m² (most common family size) |
| 34 pyeong | approx. 112.4 m² | Exclusive ~84 m² wide layout or ~99 m² |
| 40 pyeong | approx. 132.2 m² | Exclusive ~99–115 m² (large) |
| 50 pyeong | approx. 165.3 m² | Exclusive ~135 m² (premium large) |
Going the other direction — from exclusive area m² to pyeong:
| Exclusive Area (m²) | Converted Pyeong (×0.3025) | Notes |
|---|---|---|
| 39 m² | approx. 11.8 pyeong | Small studio / officetel |
| 59 m² | approx. 17.8 pyeong | 2-person household standard |
| 84 m² | approx. 25.4 pyeong | Most traded apartment size in Korea |
| 99 m² | approx. 29.9 pyeong | Mid-large |
| 115 m² | approx. 34.8 pyeong | Large |

Frequently Asked Questions
Q. How many square meters is 1 pyeong?
Exactly 400/121 m², which is approximately 3.305785 m². The shorthand "3.3 m²" is commonly used in conversation, but for large areas the rounding error adds up — the FreeSign calculator uses the full coefficient.
Q. What is the difference between exclusive area and supply area?
The exclusive area (전용면적) is the space inside your unit: rooms, living room, kitchen, and bathrooms. The supply area (분양·공급면적) adds shared spaces — corridors, stairwells, elevator lobbies — on top of that. Korean apartment listings often show the exclusive area in m², while the pyeong figure in ads may refer to the supply area. Always check which one applies before comparing prices.
Q. How many pyeong is 84 m²?
84 × 0.3025 = approximately 25.4 pyeong. The 84 m² exclusive area is the most commonly traded apartment size in Korea, often described in supply-area terms as a "32–34 pyeong apartment."
Q. Why does my result differ slightly from other calculators?
Different tools use different coefficients (3.3, 3.3058, or 3.305785) and different rounding methods, which causes minor variations. FreeSign uses 3.305785, the most precise commonly used value.
