1. What is Torque Conversion?

Torque conversion between pound-feet (lb-ft) and Newton-meters (Nm) 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:

• \( lb\text{-}ft \) — Torque in pound-feet
• \( 1.3558 \) — Conversion factor from lb-ft to Nm
• \( Nm \) — Resulting torque in Newton-meters

Explanation: This conversion allows you to translate torque values between the imperial (lb-ft) and metric (Nm) measurement systems.

3. Importance of Torque Conversion

Details: Accurate torque conversion is crucial for engineering specifications, automotive repair, mechanical design, and ensuring proper fastening torque in international projects.

4. Using the Calculator

Tips: Enter the torque value in pound-feet (lb-ft). The value must be a positive number. The calculator will automatically compute the equivalent value in Newton-meters (Nm).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 1.3558?
A: This factor comes from the relationship between pounds, feet, Newtons, and meters: 1 lb = 4.44822 N and 1 ft = 0.3048 m, resulting in 1.3558 Nm per lb-ft.

Q2: How accurate is this conversion?
A: The conversion factor 1.3558 provides precision to four decimal places, which is sufficient for most engineering and mechanical applications.

Q3: When would I need to convert between lb-ft and Nm?
A: This conversion is commonly needed when working with international specifications, automotive repair manuals from different regions, or when using tools calibrated in different units.

Q4: Are lb-ft and ft-lbs the same unit?
A: Yes, pound-feet (lb-ft) and foot-pounds (ft-lbs) represent the same torque measurement unit, though lb-ft is the more technically correct notation.

Q5: Can I convert Nm back to lb-ft?
A: Yes, to convert from Nm to lb-ft, you would divide the Nm value by 1.3558 (or multiply by approximately 0.7376).
