RPM to Watts Formula
The following formula is used to calculate the power in watts from RPM and torque.
P (W) = τ * RPM * (2 * π) / 60
Variables:
- P is the power in watts (W)
- τ is the torque in Newton-meters (Nm)
- RPM is the rotational speed in revolutions per minute
To calculate the power in watts, multiply the torque in Newton-meters by the rotational speed in RPM, then multiply by 2π and divide by 60 to convert to watts.
What is Power in Watts?
Power in watts is a unit of power that measures the rate at which energy is used or generated. In the context of rotational systems, it is a measure of how much work can be done by a rotating object over a certain period of time. It is a critical parameter in the design and analysis of motors, engines, and other mechanical systems that involve rotational motion.
How to Calculate Power in Watts from RPM?
The following steps outline how to calculate the power in watts from RPM and torque.
- First, determine the torque (τ) in Newton-meters.
- Next, determine the rotational speed (RPM).
- Use the formula P (W) = τ * RPM * (2 * π) / 60 to calculate the power in watts.
- Finally, enter the values into the calculator to verify the result.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Torque (τ) = 5 Newton-meters
RPM = 1500 revolutions per minute
