Convert Pyeong to Square feet (ft²)

The formula for pyeong to square feet

One pyeong is exactly 35.583 ft², so you multiply pyeong by 35.583 to get square feet. For example, 25 pyeong is 25 × 35.583 = 889.6 ft², and 34 pyeong is 1,209.8 ft². A small 10-pyeong unit is 355.8 ft², while a spacious 40 pyeong is 1,423.3 ft². To go the other way, divide square feet by 35.583. Because pyeong derives from a metric value, the products carry long decimals — rounding to one decimal place is plenty for a listing.

When you actually need this

You need this whenever you present a Korean home or office to an overseas partner, landlord, or platform that thinks in square feet. Writing Korea's popular 34-pyeong unit as 1,210 ft² instantly signals a three-bedroom-apartment scale to a US reader. It also comes up when listing a place on Airbnb where the area field only accepts square feet. For an international move quote or when ordering interior materials priced per ft², converting your pyeong figure up front makes the quantities easier to work out. As always, state whether the number is supply or exclusive area so the other side isn't misled.

Reference points and a common pitfall

A few anchors make estimates fast: 1 pyeong = 35.583 ft², 10 pyeong ≈ 356 ft², and 30 pyeong ≈ 1,067 ft². It helps to know that the 1,000–1,200 ft² homes common for a US family of three are about 28–34 pyeong. But Korean pyeong counts usually mean supply area (including stairwells and corridors), so a 34-pyeong unit may have only 84 m² (about 25 pyeong) of exclusive area. That exclusive 84 m² is roughly 904 ft², more than 300 ft² less than the 1,210 ft² supply figure — so always confirm which area you're converting.
