1. What is the Torque To Wattage Formula?

The Torque To Wattage formula calculates mechanical power from torque and angular velocity. It is fundamental in mechanical engineering and physics for determining the power output of rotating systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power (Watts)
• \( T \) — Torque (Newton-meters)
• \( \omega \) — Angular velocity (radians per second)

Explanation: The formula directly relates the rotational force (torque) and speed (angular velocity) to the power output of a rotating system.

3. Importance of Power Calculation

Details: Accurate power calculation is essential for designing mechanical systems, selecting appropriate motors, and evaluating the performance of rotating machinery.

4. Using the Calculator

Tips: Enter torque in Newton-meters and angular velocity in radians per second. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for torque and angular velocity?
A: Torque should be in Newton-meters (Nm) and angular velocity in radians per second (rad/s) for the result to be in Watts.

Q2: How do I convert RPM to rad/s?
A: Multiply RPM by π/30 to get rad/s (ω = RPM × π/30).

Q3: Can this formula be used for electrical motors?
A: Yes, this formula calculates the mechanical power output of electric motors and other rotating devices.

Q4: What is the relationship between power and efficiency?
A: The calculated power is the mechanical output power. Input power to a system would be higher due to efficiency losses.

Q5: Are there limitations to this formula?
A: This formula assumes constant torque and angular velocity. For variable conditions, more complex calculations are needed.
