Welcome to 180 degrees in radians, our post explaining the angle conversion. Hundred and eighty degrees are sometimes abbreviated as 180 deg, and using the degree symbol written as 180°. The result in radian can be abbreviated with the unit symbol rad. So, if you have been looking for 180 deg in rad or 180° to radians, then you are right here, too, because these are two common short forms for the unit transformation under consideration. Here you can find everything about it, including the formula and a converter you don’t want to miss.

You may change the argument in the first field, 180, our tool then does the calculation automatically, without the need to push the blue button.

## Convert 180 Degrees to Radians

Divide the angle in degrees by 180°, then multiply the term by π using the formula rad = ([180°] / 180°) × π. Thus, you get (rounded to two decimal places):
