1. What is a Torque to Watts Calculator?

Definition: This calculator converts torque (rotational force) and angular velocity to mechanical power in watts.

Purpose: It helps engineers, mechanics, and technicians determine the power output of rotating machinery.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The calculator first converts RPM to rad/s (1 RPM = 2π/60 rad/s) then multiplies torque by angular velocity to get power.

3. Importance of Torque to Power Conversion

Details: Understanding the relationship between torque and power is essential for designing and analyzing motors, engines, and rotating machinery.

4. Using the Calculator

Tips: Enter the torque in Newton-meters and angular velocity in RPM (revolutions per minute). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and power?
A: Torque is rotational force, while power is the rate at which work is done (torque × angular velocity).

Q2: How do I convert the result to horsepower?
A: Divide watts by 745.7 to get horsepower (1 HP = 745.7 W).

Q3: Why use radians per second instead of RPM?
A: The SI unit for angular velocity is rad/s, making the units consistent (Nm × rad/s = W).

Q4: Can I use this for electric motors?
A: Yes, this works for any rotating system - electric motors, engines, turbines, etc.

Q5: What's a typical torque value for small motors?
A: Small electric motors might produce 0.1-5 Nm, while car engines produce 100-500 Nm.
