Perimeter of Square Calculator

Diagonal of Square Calculator: Fast & Accurate Tool

Calculating the diagonal of a square is essential in mathematics, engineering, and design. The Diagonal of Square Calculator lets you quickly find the diagonal using either the square’s side length or perimeter, saving time and ensuring accuracy.

1. What is a Diagonal of a Square?

A square is a shape with four equal sides and four right angles. Its diagonal is the line connecting two opposite corners.

Formula for Diagonal (d) using side length (a):

d = a × √2

Formula for Diagonal (d) using perimeter (P):

1. Find the side length: a = P ÷ 4
2. Then calculate diagonal: d = (P ÷ 4) × √2
