What Is This Tool?
This tool allows users to convert torque measurements from pound-force inch (lbf·in), a common imperial unit, to newton centimeter (N·cm), an SI-derived torque unit. It is designed for applications requiring accurate translation of torque values, especially in precision engineering and small-scale mechanical systems.
How to Use This Tool?
-
Enter the torque value in pound-force inch (lbf·in).
-
Select the target unit as newton centimeter (N·cm).
-
Click convert to see the corresponding torque in newton centimeters.
-
Review the result to apply in your specific torque measurement or specification task.
Key Features
-
Converts torque from pound-force inch (lbf·in) to newton centimeter (N·cm)
-
Simple, browser-based interface for quick calculations
-
Supports torque values used in electronics, small motors, and precision tools
-

Examples
-
Convert 2 lbf·in by multiplying 2 × 11.2984833333 to get 22.5969666666 N·cm.
-
Convert 0.5 lbf·in by multiplying 0.5 × 11.2984833333 to get 5.64924166665 N·cm.
Common Use Cases
-
Specifying and calibrating tightening torque for small electronics screws and fasteners.
-
Describing output torque of small motors, gearheads, and actuators in inch-pounds converted to SI units.
-
Rating torque in precision instruments like watchmaking and dental or ophthalmic tools.
Tips & Best Practices
-
Ensure the force applied and lever arm are perpendicular as assumed in the unit definitions.
-
Use the tool primarily for low to moderate torque values typical of small fasteners and instruments.
-
Double-check converted values when precision is critical to avoid errors caused by rounding.
Limitations
-
Slight rounding errors can impact highly precise torque requirements.
-
Conversion assumes standard perpendicular force and lever arm length conditions; deviations affect accuracy.
-
Not suitable for high or industrial-scale torque conversions due to unit scale.
Frequently Asked Questions
-
Why convert pound-force inch to newton centimeter?
-
Converting allows users to translate imperial torque values to SI-derived units for consistency in precision applications and better cross-system comparisons.
-
Can this tool be used for all torque ranges?
-
The tool is designed for low to moderate torque values typical in small fasteners and instruments, not for large industrial torque levels.
-
What should I keep in mind about the unit definitions?
-
Each unit assumes a force applied perpendicular to a lever of specified length; deviations in application can affect torque results.
Key Terminology
-
Pound-force inch (lbf·in)
-
A unit of torque equal to the moment produced by one pound-force applied perpendicular to a lever arm one inch long; used in imperial engineering.
-
Newton centimeter (N·cm)
-
A unit of torque equal to the moment produced by a force of one newton applied perpendicular to a lever arm one centimetre long; equals 0.01 newton metre.
-
Torque
-
A measure of the turning or twisting force applied perpendicular to a lever arm.
