(x radians / second) x (1 revolution / 2 pi radians) x (60 seconds / minute)
= (60x) / (2 pi) (revolution / minute)
Multiply (radians per sec) by (60)/(2 pi) = 9.5493(rounded) to get RPM.

∙ 12y ago1 rpm = 2pi radians per minute = 2pi/60 radians per second = pi/30 radians per second.
.
or:
Divide rpm by 60 = revs / second, then multiply by (2 * pi).
so:
(rpm / 60) * (2 * pi) = radians per second
notes:
1 radian = 57.2957795 degrees
there are (2 * pi) radians in a circle
pi (a constant) = 3.141592654

What is the angular velocity in radians per second of a pulley turning at 1800 RPM?
The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.
What does angular speed measure?
In revolutions per minute (rpm), or radians per second.
How do you convert rpm to degrees per second?
all you have to do is convert it..........
How do you convert radians per seconds into degrees?
You cannot. Radians per second is a measure of angular speed whereas degrees are an angular measure.
If a wheel turns at 180 RPM what is it's angular velocity in radians per seconds?
180 rpm = 180/60 = 3 rps Each revolution equates to an angular movement of 2π radians. Therefore angular velocity = 3 x 2π = 6π = 18.85 radians per second (2dp)
What is the angular velocity in radians per second of a pulley turning at 1800 RPM?
The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.
What does angular speed measure?
In revolutions per minute (rpm), or radians per second.
Convert rpm to rad per sec?
1 revolution = 2π radians 1 minute = 60 seconds → 1 rpm = 1 revolution / 1 minute = 2π radians / 60 seconds = π/30 radians/seconds = π/30 rad per sec → to convert rpm to rad per sec multiply by π (pi) and divide by 30.
What is the angular speed in radians per second of a wheel that is rotating at o 18 rpm?
18 revolutions = 113.097 radians.
How do you convert rpm to degrees per second?

How do you convert radians per seconds into degrees?
You cannot. Radians per second is a measure of angular speed whereas degrees are an angular measure.
What is the angular speed of a 3000watt motor?
It's (pi x RPM)/30 radians per second.
A wheel is rotating at 250 revolutions per minute find the angular speed in radians per second?
1 revolution = (2 pi) radians1 minute = 60 seconds250 rpm = [ (250) x (2 pi) radians ] per [ 60 seconds ]= 26.18 radians per second (rounded)
If a wheel turns at 180 RPM what is it's angular velocity in radians per seconds?
180 rpm = 180/60 = 3 rps Each revolution equates to an angular movement of 2π radians. Therefore angular velocity = 3 x 2π = 6π = 18.85 radians per second (2dp)
How do you convert revolution per minute to revolution per second?
Divide the RPM by 60.
Define angular velocityWhat is its SI unit?
Angular velocity is a measurement of how fast something is turning. Everyone has heard of "RPM", which stands for "Revolutions Per Minute" ... how many complete turns an object makes in one minute. That's a perfectly good measurement of angular velocity, although in Physics, angular velocity is normally given in different units. The standard unit for angular velocity is "radians per second". Each complete turn covers (2 pi) radians (same as 360 degrees). And there are 60 seconds in one minute. So if you know the RPM, you can multiply RPM by (2 pi / 60) = 0.10472 to get angular velocity in standard units. An old LP phonograph record (remember those ?) playing at 33-1/3 RPM has an angular velocity of about 3.5 radians per second. A car engine idling at 1,000 RPM is turning at about 104.7 radians per second.
What is the relationship between linear speed and rotational speed?
(linear speed) = (rotational speed) x (radius or distance from the center) To use consistent measures, use radians/second for rotational speed, meters for the radius, and meters/second for the linear speed. If you know rotational speed in some other unit - for example, rpm (rotations per minute) - convert to radians per second first.
