# Explain RPM vs Angular Velocity | Angular Velocity to RPM Conversion | RPM to Angular Velocity Conversion

RPM vs Angular Velocity: The result is the same regardless of the differences between angular velocity and rpm (speed). Despite being more obscure than RPM, 2 pi times (radians/minute) measure the speed of rotating objects.

## RPM vs. Angular Velocity

Moreover, the RPM measurement permits determining a device’s speed since it provides how fast it rotates. Angular velocity analysis and adding data provide torque, force, work, and power.

## RPM:

Revolutions per minute can also estimate the speed at which an object rotates and express how fast a circular object spins.

A wheel’s revolution corresponds to one rotation about its axis. The wheel’s speed is 1 revolution per minute because 1 revolution equals one rotation.

Second hands rotate at one revolution per minute, or one rpm, as they complete one full rotation around the clock’s center each minute.

## Angular Velocity:

Their radius can measure circular objects in terms of how fast they spin. The angular velocity of a 360-degree rotation would be 360 degrees in one second.

A clock’s second hand rotates 360 degrees every 60 seconds, so it makes one full turn around its core every 60 seconds.

Calculating RPM from Angular Velocity

A revolution equals 360 degrees multiplied by 1/6, and a minute is similar to 60 seconds.

Each revolution equals one sixth of six degrees per second.

## Angular Velocity to RPM Conversion

The angular velocity of revolutions per minute can be converted into degrees per second by multiplying rpm by 6 since 360 degrees are enclosed in one revolution and 60 seconds in one minute.

A revolution per minute equals six degrees per second since six times one is six.

## Angular velocity is the change in angle with time.

Angular velocity is the change in angle with time. Radian per second (rad/sec) is the unit of angular velocity.

• N refers to revolutions per minute (RPM).

Both quantities can be used to express rotational speed. However, RPM is used when rotational speeds are very slow.

Putting RPM into minutes would provide a tangible value. A reasonable rotational speed is represented by rad/s.

## RPM to Angular Velocity Conversion

As you are dealing with angles, you are traveling in circles or segments of circles.

Circumference times pi equals diameter, which is determined by geometry or trigonometry. (The value of pi is about 3.14159.)

In this case, the circumference is equal to twice its diameter.

Additionally, you may have learned that a circle has 360 degrees (360°).

A circle’s angle displacement * equals its radius. Thus, one complete revolution gives 2πr/r, which leaves 2π.

Angles less than 360° can be expressed using radians or pi.

1 radian = (360°/2π) = 57.3°,

Angular velocity is measured in radians per unit time, typically per second, as opposed to linear velocity.

The velocity v of particles traveling on a circular path with a distance r from the circle’s center and a direction v perpendicular to the circle’s radius can be expressed as follows:

ω represents the Greek letter omega. The reciprocal of a second is a radian per second since v/r yields m/s divided by m or s-1. Therefore, the quantity of radians is technically unitless.
