84 m² is 25.4 pyeong of exclusive area. The '34-pyeong type' you see in sales ads refers to supply area (≈112 m², shared space included), which is why the numbers differ. Korean real-estate ads round to 0.5 pyeong by convention.
Basis: 1 pyeong = 6 ja × 6 ja = 36 ja² = 3600/1089 m² ≈ 3.3058 m² (1 ja = 10/33 m) · deeds and contracts must use m² (since 2007)
What this tool does
The Korean area converter handles the three units most used in Korean real estate, interior, and construction work: pyeong (평), square meters (㎡), and Japanese-style ja² (尺²). Using the exact ratio 1 pyeong = 3,600/1,089 ≈ 3.30579 ㎡, it converts all three units instantly and offers presets for common Korean real estate sizes (59㎡, 84㎡, 114㎡) and pyeong values (30평, 50평).
Who uses this
- Comparing Korean apartments: how many pyeong is an 84㎡ unit (= 25.41 pyeong)
- Interior estimates: convert pyeong-based prices to per-㎡ unit prices
- Architectural drawings: convert Japanese/old-Korean ja² units
- Lease contracts: convert the ㎡ in official registration to pyeong
- Vacancy allocation: convert pyeong-based rent to ㎡-based ratio
How to use
- 1Enter the area into any one of the three unit boxes (pyeong, ㎡, ja²). The other two units update automatically.
- 2Preset buttons (59㎡, 84㎡, 114㎡, 30평, 50평) apply common Korean real estate sizes with one click.
- 3Results show pyeong to two decimals, ㎡ and ja² to two decimals, plus a '0.5-pyeong rounded' value matching real estate listing conventions.
Conversion formulas (Korean standard)

Real examples
Example 1: Exact pyeong of an 84㎡ apartment
84 / 3.30579 = 25.408 pyeong. Rounded to 0.5 pyeong = 25.5 pyeong. Real estate listings of '25 pyeong' or '26 pyeong' usually refer to supply area (exclusive + common) or rounded conventions.
Example 2: 30 pyeong construction in ㎡
30 × 3.30579 = 99.17 ㎡. An interior estimate of 'KRW 1M per pyeong' for 30 pyeong is KRW 30M, which is KRW ~302,500 per ㎡.
Example 3: Japanese ja² drawing
A '108 ja²' label on a drawing → 108 × 0.0918 ≈ 9.91 ㎡ ≈ 3 pyeong. Useful when reading Japanese or old-Korean drawings.
Frequently asked questions
Exactly how many ㎡ is 1 pyeong?
1 pyeong = 3,600 / 1,089 = exactly 3.30578512... ㎡. The 3.3 ㎡ rough estimate is common but accumulates errors at larger sizes. This calculator uses the exact ratio.
What is the difference between exclusive, supply, and contract area?
Exclusive = livable space (rooms, living, bath). Supply = exclusive + shared residential (corridors, stairs). Contract = supply + other shared (parking, management). '84 ㎡' usually refers to exclusive area, while '25 pyeong type' refers to supply area roughly 80-90 ㎡.
Why is pyeong still in use?
Korea has required metric units since 1961, but real estate and interior conventions remain pyeong-based. Official deeds and contracts use ㎡, while listings and casual use prefer pyeong.
Where is ja² (尺²) used?
Old-Korean drawings, Japanese architecture, traditional medicine, and traditional furniture sizing. 1 pyeong = 36 ja², so conversion is straightforward.
Why show a '0.5-pyeong rounded' value separately?
Real estate listings typically round to 0.5 pyeong (e.g., 25.4 → 25.5). The calculator shows both the exact value and the listing-style rounded value.
Can I use this for building/floor area ratios?
No — this tool only handles unit conversion. Korean building coverage ratio (building area / lot area) and floor area ratio (gross floor area / lot area) follow zoning-specific limits and require building code calculations.
Cautions
- •1 pyeong = 3.30579 ㎡ exactly. The 3.3 ㎡ shortcut accumulates errors at large areas.
- •Real estate listings mix exclusive and supply area. Always verify the ㎡ on the official registration.
- •Ja² is an old-Korean/Japanese unit. Confirm the drawing's origin when mixing units.
- •Only ㎡ has legal force in official contracts and deeds. Pyeong is for everyday convenience.
