square centimeter to square hectometer
Convert square centimeter (cm²) to square hectometer (hm²). Use an editable area converter, conversion formula, and reference table.
1 cm² = 1e-8 hm²
Conversion formula
One square centimeter equals 1e-8 square hectometer. Multiply your value in square centimeter by this factor to get square hectometer. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 square centimeter:5 × 1e-8 = 5e-8 hm²
