Inch lbs to Foot lbs Calculator
inch lbs to foot lbs calculator Formula
Formula: ft-lb = in-lb / 12
Variables:
- Inch-Pounds (in-lb): A unit of torque representing one pound of force applied at a one-inch radius.
- Foot-Pounds (ft-lb): The standard English unit of torque, representing one pound of force applied at a one-foot radius.
What is inch lbs to foot lbs calculator?
An inch lbs to foot lbs calculator is a specialized tool used to convert torque measurements from a smaller scale (inch-pounds) to a larger, more standard scale (foot-pounds). This is critical in mechanical engineering and automotive repair where precision torque specifications are mandatory for safety and structural integrity.
Because there are exactly 12 inches in a foot, the relationship is linear. Smaller fasteners, such as those on bicycles or interior car trim, are often measured in inch-pounds, while larger structural bolts like lug nuts are measured in foot-pounds.
How to Calculate inch lbs to foot lbs (Example)
- Identify the value: Let’s say you have a torque wrench setting of 144 inch-pounds.
- Apply the formula: Divide the inch-pound value by 12.
- Equation: 144 / 12 = 12.
- Result: Your final torque is 12 foot-pounds.

Frequently Asked Questions (FAQ)
A: Inch-pounds allow for much higher precision when dealing with small, delicate fasteners where a single foot-pound difference could cause damage.
A: Yes, exactly. Since there are 12 inches in one foot, applying 1 pound of force at a distance of 12 inches is the same as applying 1 pound at 1 foot.
A: No, this specific calculator is for Imperial units. 1 ft-lb is approximately 1.355 Newton-meters.
A: Over-torquing can lead to bolt “stretch,” stripped threads, or catastrophic failure of the fastener under load.
