Enter the torque in Newton-meters and the RPM into the calculator to determine the power in kilowatts. This calculator helps in converting the mechanical power measured in torque and rotational speed to kilowatts.
Torque to kW Formula
The following formula is used to convert torque (T) and RPM (N) to power (P) in kilowatts (kW).
P (kW) = (T (Nm) * N (RPM)) / 9549.296585513720
Variables:
- P is the power in kilowatts (kW)
- T is the torque in Newton-meters (Nm)
- N is the rotational speed in revolutions per minute (RPM)
To convert torque and RPM to power in kilowatts, multiply the torque in Newton-meters by the RPM, and then divide the result by 9549.296585513720.
What is Torque?
Torque is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. Torque is typically measured in Newton-meters (Nm) in the metric system. It is an important parameter in engineering and physics as it describes the effectiveness of a force to produce rotational motion.
How to Calculate Power from Torque and RPM?
The following steps outline how to calculate the power in kilowatts from torque and RPM.
- First, determine the torque (T) in Newton-meters.
- Next, determine the rotational speed (N) in revolutions per minute (RPM).
- Use the formula from above to calculate the power (P) in kilowatts: P (kW) = (T (Nm) * N (RPM)) / 9549.296585513720.
- Finally, calculate the power in kilowatts.
- After inserting the variables and calculating the result, check your answer with the calculator above.
