This is a conversion calculator that is used to convert the angle in degrees to radians. It has a single text field where you enter the angle in degrees and three control buttons that accomplish various tasks of the calculator. After filling in the blank text field, you will click on ‘Convert' button to initiate the conversion.

The results will be displayed in radians at the bottom platform of the calculator below the controls. The ‘Reset' button is used to erase all data from the previous calculations in the calculator. It is useful when you want to perform new calculations.

For example;

Convert 60° to radians


First, enter the value 60 into the blank text field and then click the ‘Convert' button. The results will be displayed as;

Radians result:  60° × π / 180°

= 0.33333333333π rad

= 1.0471975512 rad

The degrees to radians converter will also give the angle view of the radian result. It uses a simple procedure to convert the values from degrees to radian which makes it flexible and reliable. However, it can only execute a single conversion at a time. You can always reset the calculator to give you a new space for more calculations.

Formula of converting degrees to radians

∏ Rad = 180°, which means that the Pi radians is equivalent to 180 degrees.

1° = ∏ / 180° = 0.005555556∏ = 0.01745329252 Rad. Where, one degree is equivalent to 0.01745329252 radians.

Radians = degrees x ∏ / 180°. This means that the angle in radians is calculated by multiplying the degrees by pi divided 180 degrees.

For example;

Convert 45 degrees angle to radians


Radians = degrees x ∏ / 180°


45° x 3.1459 / 180° = 0.7853981634 rad

If you have the values in radians, you will click the ‘Swap' button to alternate the flow of calculations in the converter. This allows you to perform conversions from radians to degrees.
