About Square Feet
Square feet (ft²) measure area; one ft² is a square with sides of 0.3048 m (international feet-based definitions). Real estate, interior design, and HVAC often use square feet.
About Pyeong
Pyeong is a Korean traditional area unit used in real estate practice; 1 pyeong is about 3.305785 m².
How to convert square feet to pyeong
1 square feet is equal to 0.0281031696 pyeong:
1 ft2 = (0.09290304 m² ÷ 3.3057851239669422 m²) pyeong = 0.0281031696 pyeong
Each square feet is defined as 0.09290304 m² and each pyeong as 3.3057851239669422 m², so one ft2 equals 0.09290304 ÷ 3.3057851239669422 pyeong = 0.0281031696 pyeong.
Let a(ft2) be the numeric value of the same area measured in Square Feet (ft2), and a(pyeong) the value in Pyeong (pyeong). Then:
a(pyeong) = a(ft2) × (0.09290304 / 3.3057851239669422)
Equivalently, divide by how many ft2 fit into one pyeong (m² per pyeong divided by m² per ft2):
a(pyeong) = a(ft2) ÷ 35.58317493127181
Or: pyeong = square feet ÷ 35.58317493127181
Examples
Example #1: Convert 20 ft2 to pyeong
20 ft2 = 20 ft2 × (0.09290304/3.3057851239669422) pyeong = 0.562063392 pyeong
20 ft2 = 20 ft2 ÷ 35.58317493127181 = 0.562063392 pyeong
Example #2: Convert 50 ft2 to pyeong
50 ft2 = 50 ft2 × (0.09290304/3.3057851239669422) pyeong = 1.40515848 pyeong
50 ft2 = 50 ft2 ÷ 35.58317493127181 = 1.40515848 pyeong
Summary
To convert Square Feet to Pyeong, multiply the value in ft2 by the ratio of square meters per ft2 divided by square meters per pyeong. Equivalently: value_pyeong = value_ft2 × (0.09290304 / 3.3057851239669422). Numerically, 1 ft2 equals 0.028103169600000002 pyeong.
Relationship context
Both units belong to US customary / imperial area measures. Relationships such as 9 ft² per yd² and 43,560 ft² per acre are exact under standard definitions. This tool uses SI-based square-meter factors for consistency.
