About the Hypotenuse Calculator

In a right triangle, the hypotenuse can be found from just one leg and its opposite angle, using the sine ratio, without needing the other leg at all. The known side and the hypotenuse each have their own unit selector, so you can enter one unit and read the result in another.

Formula: hypotenuse = opposite side ÷ sin(angle)

This is especially useful in surveying, navigation and physics problems where an angle of elevation or depression is measured directly.
