How many ha equals km?

Answer 1

A hectare (ha) is a unit of area, equal to 10000 square meters. A kilometer is a unit of distance equal to 1000 meters. They cannot be converted like you are asking.

If you want to convert km2 to Ha, 1 km2 = 100 Ha.

Answer 2

You can not convert between units of length and units of area. ha is hectare, a unit of area which is 10,000 square meters (think of a square 100 meters by 100 meters)
