In short
One pyeong is 3.30579 square metre, so to convert pyeong to square metre you multiply by 3.30579, and to go back you multiply square metre by 0.3025. 2 pyeong is 6.61157 square metre, 5 is 16.5289 and 10 is 33.0579. A pyeong is exactly the same area as a Japanese tsubo — 400/121 square metres, or 3.3058 m2. The useful mental figures are that a 84 m2 apartment, the most common size in Korea, is about 25.4 pyeong, and that "32 pyeong" means roughly 105 m2. Official listings have used square metres since 2007, but the pyeong never left everyday speech. The pyeong is used in South Korea, where apartment sizes are still quoted in pyeong in conversation even though listings must legally use square metres.
