The formula: multiply m² by 0.3025
To convert square meters to pyeong, use pyeong = m² × 0.3025. Going the other way, m² = pyeong × 3.3058. Here's a detail most conversion tables skip: 0.3025 is exact, not rounded. One pyeong is legally defined as 400/121 m², and its inverse, 121/400, equals exactly 0.3025. The reverse factor 3.3058 is a rounded version of 3.305785..., so it drifts by a hair on very large plots. Reach for 3.305785 whenever precision genuinely matters.
Apartment sizes, worked out
An 84 m² exclusive-area apartment is 84 × 0.3025 = 25.41 pyeong. A 59 m² unit is 17.85 pyeong, and 100 m² lands on exactly 30.25 pyeong. Reversing the math, 25 pyeong is 25 × 3.3058 = 82.6 m², and 32 pyeong is 105.8 m². A 33 m² studio officetel comes to about 9.98 pyeong, just over ten. Memorize a couple of these anchor values and you can jump between m² and pyeong in your head while scanning listings.
Don't mix up exclusive and supply area
The classic trap is that 'how many pyeong' has two possible bases. An apartment with 84 m² exclusive area (25.4 pyeong) is usually advertised as '34 pyeong,' because that headline number uses the supply area (~113 m²) that includes hallways, stairs, and shared walls. The very same home is both 25 and 34 pyeong. Note that area conversion, unlike temperature, is a pure proportion: you only multiply by a constant, with no offset to add. Korean official records list area in m² only.
Frequently asked questions
How many pyeong is 84 square meters?
84 m² × 0.3025 = 25.41 pyeong. That figure is the exclusive (private) area; the same apartment is often marketed as '34 pyeong,' which counts the larger supply area (~113 m²) including shared corridors and structural walls.
Which factor is exact, 0.3025 or 3.3058?
0.3025 (m²→pyeong) is exact, equaling 121/400 precisely. The reverse factor 3.3058 (pyeong→m²) is 400/121 = 3.305785... rounded to four decimals, so it introduces a tiny error that grows with area. Use 3.305785 for high-precision work.
Why do Korean property documents use m² instead of pyeong?
Korea adopted the metric system as its legal standard, and since 2007 the legal metric unit (m²) has been mandatory for real-estate transaction filings and advertising. Contracts and title deeds therefore show m² only, even though people still speak in pyeong in everyday conversation.
