About this converter

There is a single number field: it takes the angle in degrees. Nothing is worked out until you press Convert, and the radian answer then shows in a card below the button.

Copy writes the result together with its unit, so you can paste it straight into your own notes. Clear resets the form so you can start again with a new angle.

Degrees to radians formula

Radians = degrees × π / 180. Take the number of degrees, multiply it by π, then divide by 180.

Because π is irrational, the result is rounded rather than exact. For example, an input of 30° gives 0.523598775598299 rad, the pairing listed in the table below.
