About square centimeters and square kilometers
The Conversion Formula
To convert square centimeters to square kilometers, multiply the value by the conversion factor: 1 cm² = 1.0000e-10 km². For a worked example, suppose you need to convert 25 cm² to square kilometers: 25 × 1.0000e-10 = 2.5000e-9 km². To convert in the opposite direction, divide by 1.0000e-10, or equivalently multiply by 10000000000.
About square centimeters
The square centimeter (cm²) is a unit for small surfaces. It was the base area unit of the CGS system (centimeter-gram-second) used in early science. Today, it remains the practical choice for biology (leaf area), medicine (skin grafts), and electronics (chip sizes), where square meters are simply too big. square centimeters are commonly used in Medical skin patches, Smartphone screens, Postage stamps, and Paper sizes, Biology experiments.
A credit card covers about 46 square centimeters.
