Welcome to pi/9 radians in degrees, our post explaining the angle conversion. Pi/9 radians are usually abbreviated as pi/9 rad, and degrees are commonly written with the degree symbol °. So, if you have been looking for pi/9 rad in deg or pi/9 rad to °, 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, pi/9, our tool then does the calculation automatically, without the need to push the blue button.

Hit the swap units button only if you like to change the conversion to pi/9 ° to radians.

In the next section we discuss the math (pi = π ≈ 3.1415926535897932384626433832795).

## Convert Pi/9 Radians to Degrees

Divide the angle in radians by pi, then multiply the term by 180° using the formula deg = ([pi/9] / pi) × 180°. Thus, you get (rounded to two decimal places):

Pi/9 rad in ° = -20°
