Units explained
Feddan
A feddan is an Egyptian unit of land area equal to approximately 4200.83 m² (about 1.038 acres). Used in Egypt, Sudan, Syria, and Oman.
Originated as an Egyptian agricultural unit. Standardized at 4200.83 m² in modern Egyptian law (specifically, 333.33 qasaba squared).
Feddans are the primary unit for agricultural land in Egypt and several Arab countries. The conversion to hectares (1 feddan ≈ 0.42 hectare) is widely known regionally.
Standardized in modern Egyptian land law.
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.

Real-world example — Endurance race distances
A 50-feddan cycling or running race converts to a recognizable distance in hectares. Endurance athletes coming from a different measurement system use this conversion to compare training plans across regions.
50 feddan × 0.420083 = 21.00415 ha
Real-world example — Maritime exclusion zone
A 200-feddan exclusion zone (a common maritime boundary) converts to a different value in hectares that's useful when describing the same zone in everyday land-distance units.
200 feddan × 0.420083 = 84.0166 ha
Real-world example — Coastal cruise distances
A 10-feddan coastal sailing route converts to a different value in hectares — useful for cruise operators who switch between maritime, aviation, and road-distance units depending on the leg of the trip.
10 feddan × 0.420083 = 4.20083 ha
