One pyeong is 400/121 m², about 3.3058 m², the same as the Japanese tsubo. To go from square meters to pyeong, multiply by 0.3025: an 84 m² apartment is about 25.41 pyeong and a 59 m² apartment about 17.85 pyeong. To go from pyeong to square meters, multiply by about 3.3058, so 32 pyeong is about 105.79 m². 400/121 is the exact value; 3.3058 is its rounded form.

Where you’ll use it
South Korea has required square meters in commercial use since 1 July 2007, so listings, contracts and official records give m². Many Koreans still think of homes in pyeong, and older documents, conversations and some advertisements use it. This conversion is what you need to read an older listing, compare a remembered “32-pyeong apartment” with a metric listing, or explain sizes to someone used to pyeong.
Tip: Korean apartment sizes may be stated as exclusive area or supply area, and the two differ. Convert the same type of area when comparing listings, and rely on the square meters in the contract.
