Convert Angle from Degrees to Radians
To convert an angle from degrees to radians, multiply the angle by the constant τ (tau) divided by 360°. For example, to convert 30° to radians multiply by τ (approximately 6.283) and then divide by 360° which gives us the angle of τ/12 radians.
Observe that a full rotation in degrees is 360° and a full rotation in radians is τ radians. The constant τ is a naturally occuring number approximately equal to 6.2831853071. To convert an angle from degrees to radians, we multiply by τ over 360°. The degrees units cancel leaving us with the angle in radians.
Convert 30 Degrees To Radians
To convert the angle of 30 degrees to radians multiply by the ratio of τ (6.283) radians divided by 360°.
Convert 60 Degrees To Radians
To convert the angle of 60 degrees to radians multiply by the ratio of τ (6.283) radians divided by 360°.
