One square kilometer equals 247.10538 acres. This precise conversion factor is derived from the metric-to-imperial relationship: 1 kilometer = 0.621371 miles, so 1 square kilometer = (0.621371)² square miles = 0.386102 square miles = 0.386102 × 640 acres = 247.10538 acres. For quick mental calculations, remember that 1 square kilometer ≈ 250 acres, though the precise factor is slightly lower.
Historical development created this division: the acre evolved from medieval English agricultural practices and became standardized in the imperial system used by former British colonies including the United States, Australia, and Canada. The square kilometer emerged from the metric system adopted by France in the 1790s and subsequently by most countries worldwide. Today, this creates practical challenges for international real estate transactions, scientific research, and environmental monitoring, requiring professionals to work fluently with both systems.
