Degrees to Radians to Gradians

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

I'll let you in on another secret. $\displaystyle (\pi-3)$radians $\displaystyle \approx 8.113^{\circ}$

I assume this was a joke but I really don't get it.

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

I think Country Boy had it right. You're joking.

"Pi is the diameter around the circumference" ... definitely humorous.

"$\displaystyle \pi = 180^{\circ}$" ... definitely wrong.
