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.

What are typical applications of foot-pound and pound-force inch units?
They are commonly used in automotive repairs, mechanical assemblies, ballistics, and small actuator energy measurements.

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.
