How do I change 2.297,386,528 degrees into radians and then into gradians?

degrees to radians ... $\displaystyle \theta^\circ \cdot \frac{\pi}{180} = \phi^R$ radians to gradians ... $\displaystyle \phi^R \cdot \frac{200}{\pi} = \gamma^G$ $\displaystyle \frac{\text{degrees}}{180} = \frac{\text{grads}}{200} = \frac{\text{radians}}{\pi}$

Thankyou skeeter I'll let you in on a secret, Pi  3 = 2.297,386,528 degrees

Perhaps the use of the word secret suggested a joke. Pi is the diameter around the circumference three and a bit (irrational) times. Essentially Pi = 360 degrees. 22.187,539,92 = Circumference (Pi  3) = 2.297,386,5 degrees Here are my workings Pi / (Pi  3) = 22.187,539,92  (Pi  3) = 22.045,947,27 22.187,539,92 / 360 = 0.061,632,055 22.045,947,27 / 0.061,632,055 = 357.702,613,5 360  357.702,613,5 = 2.297,386,5

"Pi is the diameter around the circumference" ... definitely humorous. "$\displaystyle \pi = 180^{\circ}$" ... definitely wrong.
