Enter the torque in Newton-meters and the RPM into the calculator to determine the power in watts. This calculator helps in converting the rotational force and speed into electrical power output.
Torque to Watts Formula
The following formula is used to calculate the power in watts from torque and RPM.
P (W) = τ (Nm) * RPM * 2π / 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 RPM, then multiply by 2π and divide by 60.
What is Torque?
Torque is a measure of the rotational force applied to an object. It is a vector quantity, which means it has both magnitude and direction. Torque is typically measured in Newton-meters (Nm) and is a fundamental aspect of mechanics that affects the rotational motion of objects.
How to Calculate Power from Torque and RPM?
The following steps outline how to calculate the power in watts from torque and RPM.
- First, determine the torque (τ) in Newton-meters.
- Next, determine the rotational speed (RPM).
- Next, gather the formula from above = P (W) = τ (Nm) * RPM * 2π / 60.
- Finally, calculate the power (P) in watts.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Torque (τ) = 100 Newton-meters
RPM = 1500 revolutions per minute
