1. What is a Torque to Watts Calculator?

Definition: This calculator converts torque and angular velocity measurements into mechanical power in watts.

Purpose: It helps engineers and technicians determine the power output or requirement in rotational 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: Mechanical power in rotational systems is the product of torque and angular velocity.

3. Importance of Torque to Power Conversion

Details: This calculation is essential for motor selection, power transmission design, and energy efficiency analysis in mechanical systems.

4. Using the Calculator

Tips: Enter the torque in Newton-meters and angular velocity in radians per second. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert RPM to rad/s?
A: Multiply RPM by 0.10472 (2π/60) to get rad/s.

Q2: What's a typical torque value for electric motors?
A: Small motors might produce 0.1-1 Nm, while industrial motors can produce hundreds of Nm.

Q3: Can I use this for hydraulic motors?
A: Yes, the formula applies to all rotational power systems.

Q4: How does this relate to horsepower?
A: 1 horsepower ≈ 745.7 watts, so divide your result by 745.7 to get HP.

Q5: What if I only know power and need torque?
A: Rearrange the formula: \( T = \frac{P}{\omega} \)
