Units explained
Square Centimeter
A square centimeter is a metric unit of area equal to 10⁻⁴ m² (1 cm × 1 cm). It is widely used in everyday measurement, lab work, and small-area applications.
Derived by squaring the centimeter (1/100 of a meter). The centi- prefix comes from the Latin 'centum' (hundred).
Square centimeters express the cross-sectional area of pipes and cables, the surface area of small everyday objects, biological tissue samples, and many engineering quantities. The SI unit for medical/pharmaceutical dose-per-area is often expressed in cm².
Centimeter has been part of the metric system since 1795.
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.

Worked examples
Example 1 — Convert 1 cm² to feddan:
1 × 2.380482e-8 = 2.380482e-8 feddan
Example 2 — Convert 100 cm² to feddan:
100 × 2.380482e-8 = 2.380482e-6 feddan
Real-world example — Feature-scale to long-haul
One billion square centimeters equals exactly one feddan — the conversion an optical-network engineer performs when totalling feature-level path lengths into a single long-haul fiber-link distance.
1e+9 cm² × 2.380482e-8 = 23.8048195238 feddan
Real-world example — Fiber-optic link lengths
Converting from microscale square centimeters to the feddans of a long-haul fiber link is the conversion an optical engineer performs when calculating attenuation per kilometre of fiber.
1e+9 cm² × 2.380482e-8 = 23.8048195238 feddan
