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.
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.

Worked examples
Example 1 — Convert 1 pyeong to ha:
1 × 0.00033058 = 0.00033058 ha
Example 2 — Convert 100 pyeong to ha:
100 × 0.00033058 = 0.033058 ha
Real-world example — Imperial yard-to-mile scale
1,760 pyeongs equals exactly one hectare. 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 × 0.00033058 = 0.5818208 ha
Real-world example — Metric distance scale-up
One thousand pyeongs equals one hectare — 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 × 0.00033058 = 0.33058 ha
Real-world example — Imperial mile arithmetic
5,280 pyeongs equals exactly one hectare. 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 × 0.00033058 = 1.7454624 ha
