Over-tightening can strip threads or break components
Under-tightening may allow fasteners to loosen
Understanding Torque Units: Inch-pounds vs Foot-pounds
What are Inch-pounds (in-lb)?
An inch-pound (in-lb) is a unit of torque that represents the amount of rotational force applied at a distance of one inch from the center of rotation. It's commonly used for smaller fasteners and precision applications where precise torque control is essential.
When to Use Inch-pounds
- •Small screws and bolts in electronics
- •Delicate automotive components
- •Precision instruments and devices
- •Applications requiring high precision
What are Foot-pounds (ft-lb)?
A foot-pound (ft-lb) is a unit of torque representing the rotational force applied at a distance of one foot from the center of rotation. It's the standard unit for larger fasteners and structural applications where higher torque values are common.
Conversion Formula
ft-lb = in-lb ÷ 12
in-lb = ft-lb × 12
Key relationship: 1 ft-lb = 12 in-lb
Example: 24 in-lb = 2 ft-lb
Real-world Examples
Laptop Screw
Typical torque: 4-8 in-lb
Equivalent: 0.33-0.67 ft-lb
Automotive Sensor
Typical torque: 89 in-lb
Equivalent: 7.42 ft-lb
Engine Mount Bolt
Typical torque: 25 ft-lb
Equivalent: 300 in-lb
Applications and Importance
Engineering & Construction
Precise torque measurements ensure structural integrity and prevent component failure. Engineers use these conversions to specify proper tightening requirements for different applications.
Automotive Industry
Mechanics need accurate torque conversions to properly tighten components from delicate sensors (in-lb) to major structural elements (ft-lb), ensuring safety and reliability.
