Square meters, acres and pyeong
The pyeong is a traditional Korean real-estate unit, while the official measure is the square meter (m²). One pyeong is about 3.305785 m², so to convert pyeong to m² multiply by 3.3058 and divide for the reverse. Every area unit is converted through square meters.
| Unit | In m² | Note |
|---|---|---|
| Square meter (m²) | 1 m² | base unit |
| Square kilometer (km²) | 1,000,000 m² | 1 km² = 100 ha |
| Pyeong (Korean) | 3.305785 m² | 1 m² ≈ 0.3025 pyeong |
| Hectare (ha) | 10,000 m² | 100 m on a side |
| Acre | 4,046.8564 m² | about 1,224 pyeong |
| Square foot (ft²) | 0.09290304 m² | 1 ft = 0.3048 m |
For example, an exclusive area of 84 m² is 84 ÷ 3.3058 ≈ 25.4 pyeong, and 1,000 pyeong of land is 1,000 × 3.3058 ≈ 3,306 m². For more conversion tips, see the unit conversion cheat sheet.
