Understanding Torque Conversion

Torque measures rotational force and is critical in automotive engineering, mechanical design, and physics. Newton Meters (Nm) are the metric unit while Foot Pounds (ft·lb) are used in imperial systems.

Conversion Formula

1 Nm = 0.737562 ft·lb
1 ft·lb = 1.35582 Nm

Practical Examples

Automotive torque specs: 100 Nm ≈ 73.8 ft·lb (typical wheel nut torque)
Engine torque: 300 Nm ≈ 221.3 ft·lb (common diesel engine output)
Industrial applications: 500 Nm ≈ 368.8 ft·lb (machinery bolt torque)

Frequently Asked Questions

Are torque values exact between systems?

Conversions use standard factors but may have slight variations in practical applications due to rounding conventions.

Why are there different torque units?

Historical development led to different measurement systems. Nm is part of the SI system while ft·lb comes from the imperial system.

How precise are these conversions?

The conversion factors are mathematically exact, but practical applications may round to 2-3 decimal places for readability.
