The formula and where 3.3058 comes from
To convert pyeong to square meters, multiply by 3.3058, since 1 pyeong = 3.3058 m². Why that number? One pyeong is a square about 1.818 m (6 Korean cheok) on each side, so 1.818 × 1.818 ≈ 3.3058. The exact defined value is 400/121 = 3.305785 m². For example, 20 pyeong = 66.12 m², 24 pyeong = 79.34 m², and 32 pyeong = 105.79 m². To go the other way, divide by 3.3058 (1 m² ≈ 0.3025 pyeong).
Reading Korean real-estate listings
Korea's "national housing" standard of 85 m² exclusive area comes out to 85 ÷ 3.3058 ≈ 25.7 pyeong, so it's sold as a "25.7-pyeong" unit. An 84 m² apartment is 25.4 pyeong by exclusive area, yet listings call it "34 pyeong." The reason: pyeong usually counts supply area (exclusive plus shared space), while the m² on deeds and sale documents is exclusive area only. 34 pyeong of supply area is 112.4 m². Always check whether a figure means exclusive or supply area before comparing.
Rounding and other gotchas
3.3058 is rounded, so error compounds on large areas — use 3.305785 (400/121) when precision matters. Unlike temperature, area is a pure proportional scale through zero: there's no offset to add or subtract, you just multiply. Note that since 2007, m² has been Korea's legal unit for property and commerce, with pyeong surviving only as everyday shorthand. Contracts and the property register (등기부) state area in m², so do your final check in square meters.
Frequently asked questions
How many square meters is 32 pyeong?
32 × 3.3058 = 105.79 m² (105.785 m² exactly). Keep in mind a "32-pyeong" apartment is often quoted by supply area; the actual exclusive (usable) area is usually smaller, commonly around 79 m² (about 24 pyeong). Treat the two areas separately.
Why multiply by 3.3058 specifically?
One pyeong is the area of a square roughly 1.818 m (6 cheok) per side, so 1.818 × 1.818 ≈ 3.3058 m². The exact defined value is 400/121 = 3.305785… m², which is rounded to 3.3058 for everyday use.
How many pyeong is 84 m² of exclusive area?
84 ÷ 3.3058 ≈ 25.4 pyeong. But in sales and listings it's called "34 pyeong," based on supply area that adds shared common space. The two numbers describe different areas (exclusive vs supply), so don't confuse them.
