What Is This Tool?
This converter helps you transform energy values measured in foot-pounds into pound-force inches, both being units commonly used in the imperial and US customary systems for mechanical work and torque.
How to Use This Tool?
-
Enter the value in foot-pounds that you want to convert
-
Select foot-pound [ft*lbf] as the input unit
-
Choose pound-force inch [lbf*in] as the output unit
-
Submit to get the converted value using the formula: 1 ft*lbf = 12 lbf*in
Key Features
-
Converts energy values from foot-pound (ft*lbf) to pound-force inch (lbf*in)
-
Easy to use with straightforward input and output
-
Supports measurements relevant to mechanical work and torque
-
Browser-based tool requiring no installation
Examples
-
Convert 2 foot-pounds to pound-force inches: 2 ft*lbf = 24 lbf*in
-
Convert 0.5 foot-pounds to pound-force inches: 0.5 ft*lbf = 6 lbf*in
Common Use Cases
-
Measuring mechanical work in hand tools and small actuators
-
Specifying torque values in automotive repairs and mechanical assemblies
-
Converting legacy US customary engineering data involving small displacements
-
Comparing projectile energy in ballistics expressed in foot-pounds
Tips & Best Practices
-
Ensure consistent force direction and displacement units when converting
-
Use the tool for imperial/US customary measurements to maintain accuracy
-
Apply the conversion formula of 1 foot-pound equals 12 pound-force inches for reliable results
-
Double-check converted values when comparing to SI units due to possible rounding
Limitations
-
Conversion is valid only within the imperial and US customary measurement system
-
Precision may vary when converting to SI units because of rounding differences
-
Assumes consistent direction of force and displacement during conversion
Frequently Asked Questions
-
What is one foot-pound in terms of pound-force inches?
-
One foot-pound is equal to 12 pound-force inches.
-
Can this conversion be used for SI units directly?
-
No, this conversion applies strictly to imperial/US customary units and may lose precision if converted directly to SI units.

Key Terminology
-
Foot-pound [ft*lbf]
-
An imperial unit of energy representing the work done by a force of one pound-force acting through one foot of displacement.
-
Pound-force inch [lbf*in]
-
A US customary unit of energy equal to the work done by one pound-force acting through one inch of displacement.
-
Torque
-
A measure of rotational force, often expressed in units that have the same dimensions as energy such as foot-pounds or pound-force inches.
