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.

Real-world example — Track athletics distances
A 1-feddan running track equals one thousand pyeongs. Track athletes' lap pacing converts the lap (often 400 of the smaller unit) into the fractional race distance whenever a coach reviews splits.
1 feddan × 1270.7453566459 = 1270.7453566459 pyeong
Real-world example — Geographic to human-scale conversion
One feddan converts to a precise number of pyeongs — the everyday arithmetic for navigation systems, race-distance calculations, and any context where bigger geographic units must be related to the smaller working units.
1 feddan × 1270.7453566459 = 1270.7453566459 pyeong
Real-world example — Lap pacing and route segmentation
Translating a feddan-scale distance into pyeongs is how runners, cyclists, and route planners convert top-line totals into the working segments they actually pace and execute.
1 feddan × 1270.7453566459 = 1270.7453566459 pyeong
