When measuring angular speed, the unit radians per second is used. If \(N\) revolutions are performed in one minute, \( \frac {N}{60} \) revolutions are performed in one second. Fill one of the following fields, values will be converted and updated automatically. Formula and explanation, conversion. 1 second = 360/60 = 6. Through how many radians does it turn in one second? First we need to convert ω into proper units which is in radians/second. Degrees->RadiansThis program converts from degrees to radians, and from radians to degrees. θ = angle in radians (2π radians = 360 degrees) t = time, sec. The formula to find radians is θ = s/r, where the angle in radians θ is equal to the arc length s divided by the radius r.

Angular speed and angular velocity use the same formula; the difference between the two is that Angular speed is a scalar quantity, while angular velocity is a vector quantity. The annotation is instead done as a subscript of the formula sign if needed. The basic unit for angular velocity is radians per second. Revolutions per minute can be converted to angular velocity in degrees per second by multiplying the rpm by 6, since one revolution is 360 degrees and there are 60 seconds per minute.If the rpm is 1 rpm, the angular velocity in degrees per second would be 6 degrees per second, since 6 multiplied by 1 is 6. Revolutions. Then multiply the measurement in radians by 180 divided by pi. If \(N\) revolutions are performed in one minute, \( \frac {N}{60} \) revolutions are performed in one second. I can't have revolutions for delta theta and radians for acceleration. A radian is an angle where the radius is the same length as the length of the arc created by that angle. The radius in meters is, ∴r = 0.002 m However, in practice, most people prefer the use of revolutions per min (RPM). It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2 π.Thus 2 π radians is equal to 360 degrees, meaning that one radian is equal to 180/ π ≈ 57.29577 95130 82320 876 degrees..
