Square Diagonal Calculator
Calculate the diagonal of a square easily with our online calculator.
What is the Square Diagonal Calculator & How does it work?
The diagonal of a square can be calculated using the Pythagorean theorem. In a square, all sides are equal, so if the side length is a, the diagonal d forms a right triangle with two sides of length a. Therefore, the formula for the diagonal is:This formula is derived from the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the diagonal in this case) is equal to the sum of the squares of the other two sides.
d = sqrt{2} times a
d = diagonal
a = side length of the square
a = side length of the square

Frequently Asked Questions
How do I calculate the diagonal of a square?
To find the diagonal, multiply the side length by the square root of 2.
What is the formula for the diagonal of a square?
The formula is d = √2 × a, where 'd' is the diagonal and 'a' is the side length.
Can I use this calculator for any shape?
No, this calculator is specifically for squares. For other shapes, you'll need different formulas.
Why is the square root of 2 used in the formula?
The square root of 2 comes from the Pythagorean theorem applied to a right triangle formed by two sides and the diagonal of the square.
How accurate are the calculations provided by this calculator?
The calculations are as accurate as the precision of the input values and the limitations of digital computation.
Is there a way to calculate the side length from the diagonal?
Yes, you can divide the diagonal by the square root of 2 to find the side length.
What units should I use when entering the side length?
Use consistent units (e.g., all in meters or all in inches) for accurate results.
