1. What is Torque Conversion?

Torque conversion between lb-ft (pound-feet) and Nm (Newton-meters) is essential in engineering, automotive, and mechanical applications where different measurement systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( lb-ft \) — Torque in pound-feet
• \( Nm \) — Torque in Newton-meters
• \( 1.3558 \) — Conversion factor

Explanation: This formula converts torque measurements from the imperial system (lb-ft) to the metric system (Nm) using the standard conversion factor.

3. Importance of Torque Conversion

Details: Accurate torque conversion is crucial in automotive repair, engineering design, and mechanical applications where specifications may use different measurement systems.

4. Using the Calculator

Tips: Enter torque value in lb-ft. The value must be non-negative. The calculator will automatically convert it to Nm using the standard conversion factor.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1.3558 the conversion factor?
A: This factor comes from the relationship between pounds, feet, Newtons, and meters in the international system of units.

Q2: Can I convert Nm back to lb-ft?
A: Yes, to convert from Nm to lb-ft, divide the Nm value by 1.3558.

Q3: How precise is this conversion?
A: The conversion factor 1.3558 provides precision to four decimal places, which is sufficient for most practical applications.

Q4: Where is torque conversion commonly used?
A: Commonly used in automotive industry (for torque wrench settings), mechanical engineering, and any field working with both imperial and metric specifications.

Q5: Are there other torque units that need conversion?
A: Yes, other units include kg-cm (kilogram-centimeter) and oz-in (ounce-inch), but lb-ft to Nm is one of the most common conversions needed.
