Conversion Factor
Formula: 1 foot-pound (ft-lb) = 12 inch-pounds (in-lbs).
- To convert from foot-pounds (ft-lbs) to inch-pounds (in-lbs), you multiply by 12.
- To convert from inch-pounds (in-lbs) to foot-pounds (ft-lbs), you divide by 12.
Example 1: Converting from foot pounds to inch pounds: 18 ft-lbs x 12 = 216 in-lbs.
Example 2: Converting from inch pounds to foot pounds: 200 in-lbs / 12 = 16.67 ft-lbs.

Torque
Torque: Torque is a rotational or twisting force that causes an object to rotate around an axis. It is calculated as the product of force and the distance from the axis of rotation (lever arm).
Here's how torque relates to inch-pounds (in-lbs) and foot-pounds (ft-lbs):
- Inch-Pounds (in-lbs): This unit measures torque where the force is applied at a distance of one inch from the axis of rotation. For example, if a force of 1 pound-force is applied at a distance of 1 inch from the axis, the torque produced is 1 inch-pound (in-lb).
- Foot-Pounds (ft-lbs): This unit measures torque where the force is applied at a distance of one foot from the axis of rotation. For instance, if a force of 1 pound-force is applied at a distance of 1 foot from the axis, the torque produced is 1 foot-pound (ft-lb).
In summary, torque is the rotational force that inch-pounds (in-lbs) and foot-pounds (ft-lbs) quantify, depending on the distance from the axis of rotation where the force is applied.
These units are crucial in mechanical engineering, physics, and various applications where rotational forces and moments are involved.
Precision Matters
Precision matters when dealing with manufacturer torque specifications for your machinery. Go too tight and the fastener breaks, too loose and the component may fail.
Many equipment manuals and torque wrenches provide torque values in foot-pounds, while you might be more comfortable with inch-pounds. Conversion to the measurement system you are comfortable with is acceptable.
Tightening bolts and nuts to the right specifications may prevent possibly catastrophic component failure. Take the time to double check your settings to avoid making a mistake.
