How to convert from radians to degrees and vice vers?

Hi!

For example, if you have 3π/4 that means you have 3*180°/4=135 degrees

Because: π=180° so you just have to replace π to 180°

Vice vers:you just have to replace 180° to π

For example:What it means 225°?

225°=270°-45°

=3*180°/2 - 180°/4

=3π/2 - π/4

= (6π-π) / 4

=5π/4
