Units explained
Pyeong
A pyeong is a Korean unit of area equal to approximately 3.3058 m² (about 35.58 square feet).
Originated as a traditional East Asian land unit. Korean usage standardizes pyeong at 400/121 m² ≈ 3.3058 m². Defined as the area of a 6-by-6 Korean foot (cheok) square.
Pyeong is the primary unit for residential real estate in South Korea. Although the government tried to phase pyeong out in favor of square meters from 2007, the unit remains in widespread popular use, particularly for apartment sizes.
Traditional East Asian unit; remains in widespread Korean use despite government metric campaigns.
Tsubo
A tsubo is a Japanese unit of area equal to approximately 3.3058 m² (about 35.58 square feet). It is functionally identical to the Korean pyeong.
Defined as a 6-by-6 shaku square; the shaku is the traditional Japanese foot. Standardized as 400/121 m² in modern Japanese law.
Tsubos remain in widespread use in Japanese real estate, particularly for residential apartments and small commercial spaces. Property listings often cite both tsubo and square meters.
Traditional Japanese unit; legally retained in Japan for real estate.

Worked examples
Example 1 — Convert 1 pyeong to tsubo:
1 × 1 = 1 tsubo
Example 2 — Convert 100 pyeong to tsubo:
100 × 1 = 100 tsubo
Real-world example — Maritime depth conversion
A 10-pyeong sounding depth converts cleanly into tsubos. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 pyeong × 1 = 10 tsubo
Real-world example — Reference scenario in case of fallback
Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.
1 pyeong × 1 = 1 tsubo
Real-world example — Adult height conversion
A 1.8-pyeong-tall person measures a value in tsubos that converts the height to the unit favoured by American forms, schools, or driver's licences. This is daily routine for anyone living between metric and imperial systems.
1.8 pyeong × 1 = 1.8 tsubo
