Enter the value in Hectares



420 Hectares is 4.2 Square Kilometers

To convert Hectares to Square Kilometers

we know that, 1 Hectares = 0.01 Square Kilometers or
                         1 Hectares = 1/100 Square Kilometers

To convert Hectares to Square Kilometers, divide the acres value by 100

Result in Square Kilometers: 420 × hectares/100 × sq km/hectares

Cancel The Comman factor of hectares

Result in Square Kilometers: 420/100sq km

Divide the 420 by 100

Result in Square Kilometers: 4.2 square kilometers

∴ 420 Hectares = 4.2 Square Kilometers
