Frequently asked questions
How many square feet are in a square meter?
One square meter is about 10.76391 square feet, and one square foot is exactly 0.09290304 m², which is 0.3048 squared. To convert square feet to square meters multiply by 0.092903; for the reverse multiply by 10.7639. A 100 m² apartment is therefore about 1,076.39 sq ft.
How big are an acre and a hectare?
An acre is 43,560 square feet, exactly 4,046.8564224 m², or about 0.404686 hectares. A hectare is 10,000 m², about 2.471054 acres. One square kilometer is 100 hectares or about 247.1 acres, and one square mile is exactly 640 acres, which is 2.589988 km².
What is a pyeong?
Pyeong (평) is the traditional Korean unit for floor area, still quoted for apartments and shops. One pyeong is exactly 400/121 m², about 3.3058 m², the area of a square six Korean ja on each side. Multiply square meters by 0.3025 to get pyeong: an 84 m² apartment is about 25.41 pyeong. Korean law has required m² since 2007.
How do I convert square inches to square centimeters?
One square inch is exactly 6.4516 cm², because 2.54 cm squared is 6.4516. One square centimeter is about 0.155 square inches. Area factors are always the square of the length factor, so the common mistake is multiplying by 2.54 only once; for area you multiply by 2.54 twice.
How are the results rounded?
Every conversion goes through square meters and is rounded to six decimal places with trailing zeros removed. Tiny results, such as a square meter expressed in square miles, are shown with six significant figures instead so they never read as zero. Use the factor from the formula line if you need more digits.
