Torque to Watts Formula:
From: | To: |
The torque to watts conversion calculates mechanical power output from torque and rotational speed. This conversion is essential in engineering applications involving motors, engines, and rotating machinery to determine power output in watts.
The calculator uses the torque to watts formula:
Where:
Explanation: The formula converts torque and rotational speed to mechanical power, where 0.1047 is derived from converting radians per second to RPM (2π radians/60 seconds).
Details: This conversion is crucial for determining the actual power output of motors and engines, sizing electrical systems, evaluating mechanical efficiency, and comparing performance across different rotating systems.
Tips: Enter torque in Newton-meters (Nm) and RPM in revolutions per minute. Both values must be positive numbers greater than zero for accurate calculation.
Q1: Why is the conversion factor 0.1047?
A: The factor 0.1047 comes from 2π/60, which converts RPM to radians per second (the SI unit for angular velocity).
Q2: Can this formula be used for any rotating system?
A: Yes, this formula applies to any rotating mechanical system where torque and RPM are known, including electric motors, internal combustion engines, and turbines.
Q3: What's the difference between torque and power?
A: Torque is rotational force, while power is the rate at which work is done. Power combines both torque and rotational speed.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact for calculating mechanical power from torque and RPM under constant rotation conditions.
Q5: Can I convert watts back to torque?
A: Yes, you can rearrange the formula: Torque = Watts / (RPM × 0.1047) when power and RPM are known.
