Taiwan Ping (坪)
A Taiwan ping (坪) is a traditional Taiwanese floor-area unit equal to about 3.306 square meters — based on a square roughly 1.818 m per side (400/121 ft²). It is not interchangeable with mainland or Japanese area units that share similar characters.
Taiwan ping sizes apartments, office leases, and land listings in Taiwan. In Taiwan, gong jin (公斤) means kilogram — do not confuse with jin (斤) weight units.
