Calculate the area of a square from its side length. If you need to measure length and width instead, try our Rectangle Area Calculator. Results include automatic conversions to square meters, square feet, and acres.
Area represents the total surface inside a shape’s boundary. This calculator applies the standard geometry formula for this shape and multiplies the required dimensions together to produce the total area.
All calculations are performed instantly in your selected unit. Results are also converted automatically to square meters, square feet, and acres where relevant, making it easier to compare measurements across different projects.
Use A = s², where s is the side length.
Divide square feet by 43,560. For example, 87,120 ft² = 2 acres.
Yes. Calculate the square’s area, then use the acres conversion shown below the result.
