Convert area between square feet, square meters, acres, hectares, square miles and other common units. It is designed for quick estimates and everyday problem solving. When a calculation affects a contract, tax filing, medical decision or other high-stakes situation, verify the result with the appropriate professional or authoritative source.
Since 1 foot = 0.3048 meters, 100 square feet = 100 × (0.3048)² = 9.290304 square meters. The conversion factor must be squared because the measurement has two dimensions.
