How to convert Hectares to Square Kilometers
Area measurements describe surfaces — from apartment floor plans in square meters or square feet to farmland in acres and hectares, and entire countries in square kilometers or square miles.
Every area unit is a length unit squared, which is why conversion factors are large: one acre equals exactly 4,046.8564224 square meters and one hectare is exactly 10,000 square meters.
Formula
ha × 0.01 = km²
Multiply your hectares value by 0.01 to get square kilometers. For the reverse, divide by the same factor.
