Understanding Torque Units: Nm vs ft-lbs
What is Torque?
Torque is the rotational force that causes an object to rotate around an axis. It's calculated as the product of force and the perpendicular distance from the axis of rotation (lever arm).
Newton-meters (N⋅m)
The SI unit of torque, representing one newton of force applied at a distance of one meter from the rotation axis. Commonly used in metric countries and scientific applications.
Conversion Formula
ft⋅lbf = N⋅m × 0.737562
N⋅m = ft⋅lbf × 1.35582
Foot-pounds force (ft⋅lbf)
An imperial unit representing one pound-force applied at a distance of one foot from the rotation axis. Commonly used in the United States for automotive and construction applications.
Practical Example
Engine Bolt Torque
Specification: 12 ft⋅lbf
Calculation: 12 × 1.3558 = 16.27 N⋅m
Result: 16.27 N⋅m torque required
Key Differences
- •N⋅m: Metric system, international standard
- •ft⋅lbf: Imperial system, common in US
- •Conversion: N⋅m ≈ 0.74 × ft⋅lbf
