Explanation of the cm² to ha Conversion Factor
The conversion factor of 1e-8 converts square centimeters to hectares. This factor is derived from the relationship between both units and the base unit of square meters.
Definition
The square centimeter (cm²) and the hectare (ha) are both metric units of area. The hectare is defined as 10,000 square meters.
Principle
The factor arises because 1 cm² equals 0.0001 m² and 1 ha equals 10,000 m². Dividing these gives the ratio 0.0001 / 10,000 = 1e-8.
Assumptions
- The conversion uses the exact definitions of the metric units.
- The base unit for both is the square meter (m²).
Cautions
- The result should be rounded to the precision required by the specific calculation.
- The factor is exact for converting between these two defined units.
