Square kilometers to Hectares Converter

1 km² = 100 ha (square kilometer → hectare)

1 km² = 100 ha

1 square kilometer equals 100 hectares. To convert square kilometers to hectares, multiply the square kilometer value by 100. For quick reference: 1 km² = 100 ha, 5 km² = 500 ha, 10 km² = 1000 ha, 100 km² = 10000 ha.

When to use square kilometers → hectares

Square kilometers to hectares multiplies by 100. A 12 km² district contains 1,200 ha. This is among the cleanest conversions in the metric system, and it's how land-use statistics zoom in: a region reported in km² breaks down into hectare-denominated parcels for planning and agriculture. The common slip is multiplying by 1,000 by analogy with linear kilometers — the correct factor is 100.

This is the standard unit-shift for anyone working across agricultural and municipal statistics in the same metric country, since farmland is priced by the hectare but regional totals are reported in square kilometers — 3 km² is 300 ha, 0.75 km² is 75 ha, and 12.5 km² is 1,250 ha. With a clean factor of 100, this is safe to do by shifting the decimal point two places, no calculator needed even under time pressure during a live report.

About the square kilometer and the hectare

The square kilometer

The square kilometer equals one million square meters — the standard unit for city, region, and country areas in metric countries. Manhattan is about 59 km²; Istanbul is about 5,461 km²; Turkey is about 783,562 km². One km² equals exactly 100 hectares or about 0.386 square miles.

The hectare

The hectare is the metric land unit — exactly 10,000 m², a square 100 meters on each side. It's the standard for farmland, forestry, and land registration in nearly every country outside the US. One hectare is about 2.47 acres. A rugby or soccer pitch is roughly 0.7–1 hectare.
