How to Calculate

Area formulas by shape: • Rectangle: Area = Width × Height • Circle: Area = π × Radius² • Triangle: Area = Base × Height ÷ 2 Pyeong / Square meter conversion: • 1 pyeong = 3.305785 ㎡ • 1 ㎡ ≈ 0.3025 pyeong

Example

Rectangle: 5 m wide × 4 m tall Area = 20 ㎡ ≈ 6.05 pyeong Circle: radius 3 m Area = π × 9 ≈ 28.27 ㎡ ≈ 8.55 pyeong 33-pyeong apartment ≈ 109.09 ㎡
