About the Are to Hectare Converter
The are to hectare converter works within the metric land system. An are is 100 m² (a 10 m × 10 m square) and a hectare is 100 ares, or 10,000 m². Hectares are the standard unit for farmland and forests worldwide, while ares are still used for smaller plots in parts of Europe. Because the factor is exactly 100, the conversion is just a shift of the decimal point.
