WebApr 6, 2024 · To calculate the angular speed, the angle we measure is in radians. Radians are said to be a way of measuring angles where we define the right angle as pi/2 radians. Therefore one full revolution will contain around 6.28 radians. WebMay 4, 2024 · Divide both sides of this equation by 180. You get: 1 ∘ = π 180 radians. You can use this to convert the measure of an angle from degrees to radians. For example, if you wanted to convert 30 ∘ to radians, you could multiply both sides by 30: 30 ∘ = 30 ⋅ π 180 radians = 30π 180 radians = π 6 radians.
