Pyeong ↔ m² Converter
Korean real estate talks in pyeong but lists in square meters — type either and get the rest instantly.
1 pyeong = 3.3058 m² · 1 m² = 0.3025 pyeong
How to use
- Type a number in Pyeong or in m² — the other side and square feet update instantly.

Examples
Reading a Korean listing
A listing says 84㎡. That is about 25.4 pyeong (84 × 0.3025) — Korea’s most common “national size” apartment, usually marketed as a 34-pyeong home once shared areas are included.
Working out the price per pyeong
Korean property prices are quoted per pyeong (평당가) far more often than per square metre, and it is the number people compare between buildings. Divide the asking price by the size in pyeong: a 900,000,000 KRW apartment at 34 pyeong of supply area comes to roughly 26,470,000 KRW per pyeong. Two things to watch — the convention is to divide by supply area rather than exclusive area, and different listings sometimes quote different area bases, so confirm which one a per-pyeong figure came from before comparing two buildings.
Comparing a foreign apartment to a Korean one
A 1,000 ft² apartment is about 92.9㎡, which is roughly 28 pyeong of floor area. Against a Korean listing that number is closest to the 84㎡ exclusive-area layout, though the Korean unit would be advertised as 34 pyeong because that figure includes shared space. Converting in one direction only — square feet to square metres to pyeong — avoids mixing the two area bases.
Office and retail space
Commercial leases in Korea are quoted per pyeong per month (평당 임대료), usually against contract area, which adds parking and machine rooms on top of supply area. A 30-pyeong office at 80,000 KRW per pyeong is 2,400,000 KRW of monthly rent before management fees. Because the area base is wider than for apartments, converting an office from square metres to pyeong and then comparing it against an apartment per-pyeong figure is not a like-for-like comparison.
Land and site share
For an apartment, land is not the floor area you live on — it is the site share (대지지분), your slice of the plot the building stands on, and it is registered separately in square metres. Older low-rise blocks often carry a large site share relative to their floor area, which is why redevelopment value is discussed in pyeong of land rather than pyeong of home. Convert the site share on its own; adding it to floor area produces a number that means nothing.
FAQ
What is a pyeong (평), and what is it worth exactly?
Pyeong is a traditional East Asian unit of area, historically the floor space of two tatami mats. It is defined exactly, not approximately: one pyeong is 400/121 square metres, which works out to 3.30578512… ㎡. This tool converts with that exact fraction and rounds only the number it displays, so repeated conversions do not drift. Korea moved official documents to square metres in 2007, but pyeong remains how apartment and office size is discussed in practice.
What are the conversion formulas?
Square metres = pyeong × 400 ÷ 121, and pyeong = square metres × 121 ÷ 400. For mental arithmetic, multiply by 3.31 or by 0.3025 — close enough to judge a listing, though a few hundredths off on large floor areas. Square feet are derived from the square-metre value (1㎡ = 10.7639 ft²). Pyeong and square metres are shown to two decimals and square feet to one, which is why converting a rounded figure back may differ in the last digit.
Why does a “34평 apartment” not mean 34 pyeong of living space?
Because Korean listings use more than one kind of area. Exclusive area (전용면적) is the space inside your own front door — the number that appears in the register and in the legal listing. Supply area (공급면적) adds a share of the corridors, stairwells and other common parts of the building, and it is the number marketing usually converts into 평. So an apartment sold as “34평” is 34 pyeong of supply area; its exclusive area is smaller, commonly listed as 84㎡. The ratio between the two varies by building, so it cannot be computed — always check which area the listing states.
What is the “national size” (국민평형) apartment?
An informal name for the 84㎡ exclusive-area layout, the most common apartment size in Korea. 84㎡ is about 25.4 pyeong of exclusive area, while the same unit is typically advertised as a 34-pyeong home by supply area. Seeing both numbers for one apartment is normal, not an error.
What is the exclusive-area ratio (전용률), and what is normal?
It is exclusive area divided by supply area — how much of what you pay for sits inside your own front door. Apartments typically land between 70% and 80%. Officetels are much lower, often in the 50s, because their shared corridors and lobbies are larger relative to unit size, which is why an officetel advertised at the same pyeong figure as an apartment gives noticeably less living space. The ratio is a property of the building, not something that can be derived from the pyeong number alone.
If pyeong was abolished in 2007, why is it still everywhere?
What changed in 2007 was enforcement of the statutory measurement units: official documents, contracts and advertisements have to state area in square metres, and using pyeong in them carries a fine. Speech was never regulated. Buyers, agents and builders all had decades of intuition calibrated in pyeong, and “84 square metres” does not summon a mental picture the way “34 pyeong” does. So listings show ㎡ and conversations use 평 — which is exactly the gap this converter sits in.
How does square feet fit in?
Square feet are converted from the square-metre value at 1㎡ = 10.7639 ft², so 1 pyeong is about 35.58 ft². The unit is not used in Korean property at all; it is here for people comparing a Korean listing against a home measured in feet. Note that floor area in the United States is usually quoted closer to Korea’s exclusive area than to supply area, so comparing a US square-footage figure against a Korean supply-area pyeong figure overstates how much smaller the Korean home is.
