Whether you're browsing Seoul real estate listings or planning office layouts in Busan, understanding pyeong conversions becomes crucial when dealing with Korean space measurements. This traditional unit persists in everyday use despite the country's official metric system adoption. Let's explore how to bridge these measurement worlds effectively.
Unit definitions
What is a square meter (m²)?
- Description: The SI unit for area measurement
- Symbol: m²
- Common uses: Global real estate, construction plans, land surveys
- Definition: Area of a square with 1-meter sides (1m × 1m)
What is a Korean pyeong (坪)?
- Description: Traditional East Asian area unit
- Symbol: 坪 (Korean) / py (English)
- Common uses: Korean property listings, interior design
- Definition: 1 pyeong = 3.3058 m² (based on 6 Korean feet per side)
Conversion formula
The standardized conversion equation: 1 m² = 0.3025 pyeong
This ratio comes from:
1 pyeong = 400/121 m² ≈ 3.3058 m²
Thus:
1 m² = 1 ÷ 3.3058 ≈ 0.3025 pyeong
Example calculations
- Converting 85 m² apartment to pyeong:
85 × 0.3025 = 25.7125 → 25.7 pyeong - Reverse conversion (30 pyeong office space):
30 ÷ 0.3025 = 99.1735 → 99.2 m²

Historical background
The pyeong's origins trace back to China's Tang dynasty measurement systems, later adapted in Korea during teh Three Kingdoms period (57 BCE – 668 CE). Modern standardization occurred in 1959 when South Korea defined 1 pyeong as exactly 3.3058 m² through the Measurement Act. Interestingly, this unit survived multiple metrication campaigns – a testament to cultural attachment in housing markets.
Interesting facts
- Visual reference: 1 pyeong equals two traditional Korean floor mats (tatami-style)
- Urban living: Average Seoul apartment = 25-30 pyeong (83-99 m²)
- Global cousins: Nearly identical to Japanese tsubo (1 tsubo = 1 pyeong)
- Legal quirk: Since 2007, Korean law requires dual pyeong/m² listings
- Construction math: Korean builders often calculate material costs per pyeong
FAQ
The standard conversion (1 m² = 0.3025 pyeong) is precise for most practical uses, though historical variations occasionally appear in older documents.
Pyeong remains popular in real estate due to cultural familiarity, though official documents increasingly use square meters.
No, it’s uniquely Korean. Japan uses a similar unit called tsubo (1 tsubo = 1 pyeong), but terminology differs.
While possible, we recommend including square meter equivalents for clarity in global transactions.
About 33 square meters – roughly the size of a studio apartment in Seoul’s urban areas.
