## waheguru Group Title How do we convert degrees to rad and rad to degrees? one year ago one year ago

1. TuringTest Group Title

$\pi\text{ radians }=180^{\circ}$

2. waheguru Group Title

Yea But what is the formula ?

3. waheguru Group Title

For example convert 3pi/4 rad to degrees

4. TuringTest Group Title

$x\text{ rad }\times({180^{\circ}\over\pi\text{ rad }})=y^{\circ}$

5. TuringTest Group Title

this works because by the formula I first typed we have that$({180^{\circ}\over\pi\text{ rad}})=1$so multiplying a number by that changes nothing to gr from degrees to radians we go the other way and use$({\pi\text{ rad }\over180^{\circ}})=1$
