How do you convert rpm to radians?

It is not possible. Radians are a measure of angular displacement while rpm is a measure of the rate of change of angular displacement. The question is like asking to convert speed into distance.


How do you Convert revolution per minute to liters?

You cannot in any sensible way. RPM is a measure of (angular) velocity whereas litres is a measure of volume. Your hard disk will have an rpm but what does litres mean in terms of the disk?


What does angular speed measure?

In revolutions per minute (rpm), or radians per second.


How fast is mach 0.8 or 272.23 meters per second in RPM?

To convert speed from meters per second (m/s) to revolutions per minute (RPM), you need to know the circumference of the rotating object. Without that information, it is not possible to directly convert mach 0.8 or 272.23 m/s to RPM. RPM is a measure of rotational speed, whereas mach is a unit of relative velocity to the speed of sound.


How do you measure distance based off of RPM?

RPM is revolutions per minute. You can not measure distance without knowing the radius or diameter of what that revolves. With diameter or radius you can calculate the circles outer length. Formulas for this is: With Radius: 2*pi*r, With Diameter: pi*d, where pi is approx 3,14 (accurate enough for most calculations but pi is in fact an endless series of numbers, 3,14159265 and billions more decimals) This length can be multiplied directly with RPM and you get total distance per minute. An engine running but standing still will however not move and the calculated answer does not have to indicate actual distance travelled.

What does RPM measure?

it measures rotation per minute


Can revolution per minute convert to liters per minute?

No, revolutions per minute (RPM) and liters per minute (L/min) are two different units of measure that cannot be directly converted to each other without additional information like the size of the object being rotated and its volumetric capacity. RPM is a measure of rotational speed, while L/min is a measure of volume flow rate.

Is there a way to amplify torque without losing rpm?

No.


How can you measure electric motor RPM without a strobe?

Two methods, one uses a dial that is held in the center of the revolving shaft and is directly read off of the dial face. The second method uses a strobe light. The light is focused on the shaft and the dial on the strobe is turned until it looks like the shaft has come to a stand still. The RPM is read off of the meter face of the strobe light.


What is the rpm for the speed of sound?

The speed of sound is approximately 343 meters per second (at standard conditions). There is no direct conversion from speed of sound to rpm (revolutions per minute), as rpm is a measure of rotational speed, while the speed of sound is a measure of how quickly sound waves travel through a medium like air.


What is rpm full form?

Revolutions per minute, a measure how fast something is rotating.
