1. What is a Torque to Power Calculator?

Definition: This calculator converts torque and rotational speed into mechanical power.

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

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 torque value is multiplied by the angular velocity (converted from RPM to rad/s) to calculate power in Watts.

3. Importance of Torque-Power Calculation

Details: Understanding the relationship between torque and power is essential for designing and analyzing mechanical systems, selecting motors, and evaluating performance.

4. Using the Calculator

Tips: Enter the torque in Newton-meters and rotational speed in RPM. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between torque and power?
A: Torque is a 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 the Watts result by 745.7 to get horsepower (hp).

Q3: Why convert RPM to rad/s?
A: The SI unit for angular velocity is rad/s, which gives power in Watts (the SI unit) when multiplied by Nm.

Q4: Can I use this for electric motors?
A: Yes, this applies to any rotating system including electric motors, engines, and turbines.

Q5: What if my torque is in lb-ft instead of Nm?
A: First convert lb-ft to Nm by multiplying by 1.355818, then use the calculator.
