Definition of Square Kilometer
- Definition

km² — The square kilometer is an SI-derived unit of area equal to exactly 1,000,000 m² (one million square meters). It represents the area of a square with sides of 1 kilometer.
The square kilometer is the standard unit for expressing large geographic areas such as countries, states, cities, lakes, national parks, and ecological regions. It is used globally in geography, cartography, and environmental science.
One square kilometer equals exactly 100 hectares or 10,000 ares. These relationships are exact because all three units are defined as powers of ten of the square meter.
- Exact factor
- 1 km² = 1,000,000 m²
- Examples
-
- 5,300 km² = 5,300,000,000 m²
- 5,300 km² = 57,048,725,209 ft²
- 39 km² = 15.058 mi²

yd² — The square yard is a unit of area in the US customary and British imperial systems. It is defined as the area of a square with sides of exactly 1 yard (0.9144 meter), which gives an exact metric equivalent of 0.83612736 m².
The square yard is commonly used in the United States and the United Kingdom for measuring medium-sized areas such as flooring, carpeting, paving, and landscaping materials.
One square yard equals exactly 9 square feet or 1,296 square inches. These relationships are exact because 1 yard = 3 feet = 36 inches by definition.
- Exact factor
- 1 yd² = 0.83612736 m²
- Examples
-
- 5.98 yd² = 53.82 ft²
- 53 yd² = 443,147.5 cm²
- 940 yd² = 0.000786 km²
About the Square Kilometer
Facts & Uses
- 1 km² = 1,000,000 m² exactly = 100 hectares. The metric unit for large geographic areas: cities, countries, lakes, forests.
- Standard in geography (country and region sizes), environmental science (deforestation, conservation areas), and urban planning.
- Used in satellite imagery analysis, land use statistics, and population density (people per km²).
- Reference scales: 1 km² ≈ small village, 100 km² ≈ small town, 1000 km² ≈ large metropolitan core, 1,000,000 km² ≈ medium-sized country.
Curiosities
- Vatican City is the smallest country at 0.49 km²; Russia is the largest at over 17 million km². Earth's total surface is about 510 million km² (71% ocean).
- The Amazon rainforest covers approximately 5.5 million km² across nine countries — about the size of the contiguous US west of the Mississippi.
- Population density extremes: Monaco ~26,000 people/km²; Mongolia ~2 people/km² — a 13,000× difference.
- Approximate equivalents: 1 km² ≈ 0.386 mi² ≈ 247 acres ≈ 100 hectares.

About the Square Yard
Facts & Uses
- 1 yd² = 9 ft² = 0.83612736 m² exactly. The traditional unit for fabric and carpet sales in the US and UK.
- Standard for carpet pricing (per yd²), fabric and upholstery, landscape materials (mulch, gravel coverage), and concrete pours.
- Used in football field calculations: an American football field is 5,531 yd² (300 × 160 ft); a soccer pitch is around 8,000 yd².
- Convenient because fabric bolts are typically 1-1.5 yards wide, so width × length naturally produces square yards.
Curiosities
- Many US carpet retailers price by the square yard, while flooring (tile, laminate) prices by the square foot — a frequent source of cost comparison errors (1 yd² = 9 ft²).
- The yard was historically defined as the distance from the king's nose to fingertip; the international yard is now exactly 0.9144 m by 1959 agreement.
- A standard cubic yard of concrete covers about 81 ft² at 4 inches thick — useful for sidewalk and patio estimates.
- Approximate equivalents: 1 yd² ≈ 0.836 m² = 9 ft² = 1296 in².
