Square Side Length
Online calculator allows you to quickly determine the length of a square's side based on the given area or perimeter.
If the area of the square is known S, then its side length a is calculated as the square root of the area, formula: a = √S.
If the diagonal of the square is known d, then its side length a can be calculated using the following formula: a = d / √2
If the perimeter of the square is known P, then its side length a is calculated as: a = P / 4.
