1. What is Torque Conversion?

Torque conversion between foot-pounds (ft-lb) 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:

• \( ft\text{-}lb \) — Torque in foot-pounds
• \( Nm \) — Torque in newton meters
• 1.3558 — Conversion factor (exact value)

Explanation: One foot-pound is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point, equivalent to 1.3558 newton meters.

3. Importance of Torque Conversion

Details: Accurate torque conversion is crucial for engineering specifications, automotive repairs, and mechanical applications where different measurement systems are used.

4. Using the Calculator

Tips: Enter torque value in foot-pounds. The calculator will automatically compute the equivalent value in newton meters.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between ft-lb and Nm?
A: Different industries and countries use different measurement systems. Automotive often uses ft-lb while engineering typically uses Nm.

Q2: Is the conversion factor exact?
A: Yes, 1 ft-lb is exactly 1.355818 Nm, though we use 1.3558 for practical calculations.

Q3: When is torque measurement important?
A: Critical for bolt tightening, engine specifications, and any rotating machinery where precise rotational force matters.

Q4: Can I convert Nm back to ft-lb?
A: Yes, divide Nm by 1.3558 to get ft-lb (or multiply by 0.737562).

Q5: What's the difference between ft-lb and lb-ft?
A: They represent the same unit of measurement, just written differently.
