How to convert Square Centimeters to Square Kilometers
To convert square centimeters to square kilometers, multiply by 1 × 10⁻¹⁰. One square centimeter equals 1 × 10⁻¹⁰ km², and one square kilometer equals 10,000,000,000 cm².
- Take the value in square centimeters — for example 7.5 cm².
- Multiply by 1 × 10⁻¹⁰ (the number of square kilometers in one square centimeter).
- 7.5 × 1 × 10⁻¹⁰ = 7.5 × 10⁻¹⁰ km².
Shortcut: the factor is a power of ten, so just move the decimal point 10 places to the left.

The units
A square 1 cm on each side.
Used for: Small surfaces, labels and wound dressings.
A square 1 km on each side — 1,000,000 m² or 100 hectares.
Used for: City, country and land areas.
Area factors are the squares of exact length factors, so they are exact too (an international acre is exactly 4,046.8564224 m²).
