How to Convert Square Kilometer to Square Hectometer
To convert km² to mi²: multiply by 0.3861. To hectares: multiply by 100. To acres: multiply by 247.105.
1 km² = 1,000,000 m² = 100 ha = 247.105 acres ≈ 0.3861 mi².
For example, 1 Square Kilometer (km²) = 100 Square Hectometer (hm²).

About Square Kilometer (km²)
Definition
The square kilometer is a metric unit of area equal to 1,000,000 square meters, or a square with sides of 1 kilometer.
Mathematical Relationship
1 km² = 1,000,000 m² = 100 ha = 247.105 acres ≈ 0.3861 mi².
Conversion Formula
To convert km² to mi²: multiply by 0.3861. To hectares: multiply by 100. To acres: multiply by 247.105.
Practical Applications
Country areas, national park sizes, city footprints, forest coverage, and watershed boundaries.
Interesting Facts
Vatican City = 0.44 km². Manhattan = 59.1 km². Russia = 17,098,242 km² (largest country). Earth's surface = 510,072,000 km².
Common Mistakes
Thinking 1 km² = 1,000 m² (it's actually 1,000,000 m²). Area scales as the square of the linear dimension.
Educational Tips
1 km = 1,000 m, but 1 km² = 1,000² m² = 1,000,000 m². Always square the conversion factor for area.
About Square Hectometer (hm²)
Definition
The square hectometer is a metric unit of area equal to 10,000 square meters — also known as a hectare.
Mathematical Relationship
1 hm² = 10,000 m² = 1 ha = 100 are = 0.01 km².
Conversion Formula
To convert hm² to acres: multiply by 2.471. To km²: divide by 100. To m²: multiply by 10,000.
Practical Applications
Farm sizes, vineyard areas, national park land parcels, and urban development projects.
Interesting Facts
A standard FIFA football pitch is about 0.7 ha. The Louvre Museum covers about 6 ha.
Common Mistakes
Not realizing hm² and hectare are the same thing. Also, confusing hectare (area) with hectometer (length).
Educational Tips
A hectare = a square 100 m × 100 m. Picture a large athletic field — that's roughly 1 hectare.
