About the hectare and the square kilometer
A hectare is a square of 100 m by 100 m. Land area in most countries is measured in hectares, and one hectare is about 2.47 acres.
A square kilometer is one million square meters, or 100 hectares. It describes cities, lakes and countries; Monaco covers about 2 km².
One square kilometer equals 100 hectares, which makes the square kilometer the larger unit of the two.
