Quick Reference
- 10 pyeong ≈ 33.06 m² ≈ 355.83 ft²
- 25 pyeong ≈ 82.64 m² ≈ 889.58 ft²
- 33 pyeong ≈ 109.09 m² ≈ 1,174 ft² (typical Korean 32–34 pyeong apartment)
- 84 m² ≈ 25.41 pyeong (Korean national-housing standard)
Formula and decision logic
1 pyeong (평) is exactly 400/121 m² (≈ 3.3058 m²). This converter shows the same area in pyeong, square meters, and square feet at once.
1 평 = 400/121 m² ≈ 3.3058 m²
1 m² = 121/400 평 ≈ 0.3025 평 ≈ 10.7639 ft²

How to read the result
- Real-estate listings in Korea historically use “전용면적” (exclusive area) in m² but everyday conversation still references 평.
- Square feet helps cross-check with overseas listings; 1 평 is roughly 35.58 ft².
Common input mistakes
- Treating 1 평 as exactly 3.3 m² (it is closer to 3.3058 m²; small differences add up on large units).
- Mixing 공급면적 (supply area, includes common space) with 전용면적 (private area) when comparing apartments.
Frequently asked questions
What is 1 pyeong in m²?
Exactly 400/121 m² (≈ 3.3058 m²). Rounding to 3.3 m² is common but introduces error on large areas, so this calculator uses the exact ratio.
Why does my 84 m² apartment look like both 25 and 34 pyeong?
Korean apartments are described both by exclusive area and supply area (includes shared corridors and stairs). 84 m² exclusive ≈ 25 pyeong; the corresponding supply area ≈ 34 pyeong.
How big is 1 pyeong in square feet?
About 35.58 ft². The converter shows pyeong → m² → ft² together.
Can I enter ft² and get pyeong back?
Yes. Pick ft² in the unit selector and the calculator will show the matching pyeong and m² values.
