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.
Dunam (Metric)
A metric dunam is a unit of land area equal to exactly 1000 m² (0.1 hectare or about 0.247 acre). Used widely in Israel, Turkey, and the Middle East.
Originally an Ottoman unit of variable size (see Ottoman dunam). The metric dunam was standardized at exactly 1000 m² in the 20th century for ease of conversion.
Metric dunams are the standard land measurement unit in Israel for both residential and agricultural property. Also widely used in Turkey, Cyprus, and other former Ottoman territories.
Standardized at 1000 m² in 20th century; Ottoman origin.

Worked examples
Example 1 — Convert 1 pyeong to dunam:
1 × 0.0033058 = 0.0033058 dunam
Example 2 — Convert 100 pyeong to dunam:
100 × 0.0033058 = 0.33058 dunam
Real-world example — Metric distance scale-up
One thousand pyeongs equals one dunam (metric) — the running distance for a 1K race or the standard metric kilometre-scale step. The simple thousand-fold conversion is the most-used metric distance translation.
1000 pyeong × 0.0033058 = 3.3058 dunam
Real-world example — Imperial mile arithmetic
5,280 pyeongs equals exactly one dunam (metric). American hikers tracking elevation gain in the smaller unit but trail length in the larger one use this constant every time they read a topographic map.
5280 pyeong × 0.0033058 = 17.454624 dunam
Real-world example — Imperial yard-to-mile scale
1,760 pyeongs equals exactly one dunam (metric). American athletes and surveyors use this conversion to translate distances quoted in the smaller imperial unit into recognizable fractions of the larger geographic one.
1760 pyeong × 0.0033058 = 5.818208 dunam
