Definition: RPM stands for Revolutions Per Minute. It is a unit used to measure the rotational speed of an object, indicating how many complete rotations the object makes in one minute.
Uses: RPM is commonly used to describe the speed of rotating machinery, such as motors, engines, fans, hard drives, and wheels. For example, the RPM of a car's engine or a computer's cooling fan is often measured to assess performance.
Formula: RPM can be calculated using the formula:
RPM = (Number of Revolutions) / (Time in Minutes)
Definition: deg/s stands for Degrees Per Second. It is a unit used to measure angular velocity, indicating how many degrees an object rotates in one second.
Uses: deg/s is commonly used in applications where precise angular motion is critical, such as robotics, aerospace, and gaming controllers. For example, the angular velocity of a robotic arm or a drone's propeller is often measured in deg/s.
Formula: deg/s can be calculated using the formula:
deg/s = (Angle in Degrees) / (Time in Seconds)
RPM and deg/s are both units used to measure rotational speed, but they represent it in different ways. RPM measures the number of complete rotations per minute, while deg/s measures the angular displacement per second.
Conversion Formula:
deg/s = RPM × 6
This is because one complete rotation is 360 degrees, and there are 60 seconds in a minute. Therefore:
deg/s = (RPM × 360 degrees) / 60 seconds = RPM × 6
For example, if an object rotates at 10 RPM, its angular velocity in deg/s would be:
deg/s = 10 × 6 = 60 deg/s
| RPM | Degrees per Second (°/s) |
|---|---|
| 1 rpm | 6 °/s |
| 5 rpm | 30 °/s |
| 10 rpm | 60 °/s |
| 50 rpm | 300 °/s |
| 100 rpm | 600 °/s |
| 1000 rpm | 6000 °/s |
| 5000 rpm | 30000 °/s |
