What Is This Tool?
This converter allows users to translate measurements of small mechanical torque or energy from ounce-force inch, a non-SI unit, into pound-force inch, a common US customary unit. It is designed for precision hardware, consumer electronics, and mechanical engineering applications.
How to Use This Tool?
-
Enter the value in ounce-force inch (ozf·in) you want to convert
-
Select ounce-force inch as the input unit and pound-force inch as the output unit
-
Click the convert button to get the equivalent value in pound-force inch (lbf·in)
Key Features
-
Converts energy values between ounce-force inch and pound-force inch units
-
Supports measurements commonly used in precision hardware and legacy engineering data
-
Browser-based and easy to use without installation
Examples
-
10 ozf·in equals 0.625 lbf·in
-
16 ozf·in equals 1 lbf·in
Common Use Cases
-
Specifying small torques for precision components like watches or camera lenses
-
Rating torque output of small servos or gearbox stages in consumer electronics
-
Converting legacy mechanical energy measurements from ozf·in to lbf·in for compatibility
Tips & Best Practices
-
Use this tool to ensure accurate translation between non-SI and US customary units
-
Apply conversions primarily for small scale torque and energy values
-
Verify units carefully when working with legacy or mixed measurement systems
Limitations
-
Ounce-force inch is a non-SI unit not always recognized in international standards
-
Rounding can affect precision with very small torque values
-
Suitable mainly for small torque and energy; not intended for larger scales
Frequently Asked Questions

Key Terminology
-
Ounce-force inch [ozf·in]
-
A non-SI unit of energy or torque equal to the moment produced by one avoirdupois ounce acting through a one-inch lever arm.
-
Pound-force inch [lbf·in]
-
A unit of mechanical energy equal to work done by one pound-force over a one-inch displacement, commonly used in US customary systems.
-
Torque
-
A measure of the moment of force that causes rotation about an axis.
