Pyeong to square meters converter
Pyeong (평) is the traditional Korean unit of floor area, still widely used when people talk about apartments and offices in Korea. Official documents use square meters. This converter switches between the two.
One pyeong is exactly 400/121 square meters, about 3.3058 m².
How to use
- Choose pyeong → m² or m² → pyeong.
- Enter the area. Decimals are allowed.
- Read the result, rounded to two decimal places.
How it works
One pyeong is the area of a square 6 ja on each side. One ja is 10/33 m, so one pyeong = (6 × 10/33)² = 400/121 m² ≈ 3.305785 m².
Pyeong → m²: pyeong × 400 ÷ 121.
m² → pyeong: m² × 121 ÷ 400, the same as multiplying by about 0.3025.
Results are rounded to two decimal places.
Example
Thirty pyeong is 30 × 400 ÷ 121 ≈ 99.17 m². An apartment with 84 m² of exclusive area is 84 × 121 ÷ 400 = 25.41 pyeong, and 59 m² is about 17.85 pyeong.
For a quick estimate, multiply pyeong by 3.3 or square meters by 0.3, but the error grows with larger areas.
Good to know
- Korean apartment "pyeong types" usually describe supply area, which includes shared spaces, so they are larger than the exclusive area converted to pyeong.
- Contracts and official records in Korea state area in square meters. Use those figures when signing anything.
