What Is This Tool?
This tool converts values of torque or energy from ounce-force inch (ozf·in), a non-SI unit used for small torques, to inch-pound (in·lbf), a commonly used US customary unit for torque and energy. It helps translate small mechanical measurements into a widely recognized unit for engineering and precision applications.
How to Use This Tool?
-
Enter the torque or energy value in ounce-force inch (ozf·in)
-
Select ounce-force inch as the input unit and inch-pound as the output unit
-
Click convert to get the equivalent value in inch-pound (in·lbf)
-
Use the result for engineering, testing, or documentation purposes
Key Features
-
Converts from ounce-force inch (ozf·in) to inch-pound (in·lbf) with a fixed rate
-
Supports small-scale torque and energy conversions for precision hardware
-
Browser-based and easy to use without requiring complex formulas
-
Useful for translating legacy mechanical specifications into customary units
Examples
-
Convert 10 ozf·in: 10 × 0.0625 = 0.625 in·lbf
-
Convert 16 ozf·in: 16 × 0.0625 = 1.0 in·lbf
Common Use Cases
-
Specifying small torques for precision components like watch parts or camera lenses
-
Rating torque output of small servos or gearboxes in consumer electronics
-
Describing torque or energy in legacy mechanical datasheets
-
Setting small torque values on wrenches and hand tools in electronics assembly
-
Testing mechanical properties of springs, clamps, or other small components
Tips & Best Practices
-
Ensure input values represent small-scale torque or energy
-
Remember the conversion factor is 0.0625 for ozf·in to in·lbf
-
Use this tool primarily for legacy units or precision applications
-
Consider SI units if dealing with larger torque or energy values
-
Be mindful of rounding when working with precise instruments
Limitations
-
Ounce-force inch is a non-SI unit and less frequently used in modern engineering
-
The conversion applies best to small torque/energy amounts, not large values
-
Rounding errors may occur due to the fractional conversion factor
-
Different unit conventions might cause confusion without clear documentation
Frequently Asked Questions
-
What does one ounce-force inch represent?
-
It represents the torque produced by a force of one avoirdupois ounce acting through a one-inch lever arm.
-
Why convert from ounce-force inch to inch-pound?
-
This conversion translates small torque values from a legacy or metric-related unit into a more commonly used US customary unit for easier engineering use.
-
Is inch-pound a unit of energy or torque?
-
Inch-pound is a unit representing energy or torque, defined as one pound-force applied over a one-inch distance.
Key Terminology
-
Ounce-force inch (ozf·in)
-
A non-SI unit of torque or energy equal to a force of one avoirdupois ounce applied at one inch lever arm.
-
Inch-pound (in·lbf)
-
A customary unit of torque or energy equal to one pound-force acting through a distance of one inch.
-
Torque
-
A measure of rotational force typically expressed as force multiplied by distance.
