What Is This Tool?
This converter allows you to transform torque values measured in ounce-force inch into gram-force centimeter units. Both units are used to specify very small torque moments, often in electronics, watchmaking, and precision instrument calibration.
How to Use This Tool?
-
Enter the torque value in ounce-force inch (ozf*in) in the input field.
-
Select the target unit as gram-force centimeter (gf·cm).
-
Click the convert button to get the equivalent torque value.
-
Use the result to understand or specify small torque values in gram-force centimeters.
Key Features
-
Converts torque between ounce-force inch and gram-force centimeter units.
-
Supports measurements commonly used in electronics assembly and precision instruments.
-
Shows exact conversion based on a precise conversion rate.
-
Browser-based and easy to use with quick input options.
-
Appropriate for use in miniature robotics, watchmaking, and torque calibration.
Examples
-
Convert 2 ozf·in to gf·cm: 2 × 72.0077906319 = 144.0155812638 gf·cm
-
Convert 0.5 ozf·in to gf·cm: 0.5 × 72.0077906319 = 36.00389531595 gf·cm
Common Use Cases
-
Specifying torque limits for small screws and connectors in electronics assembly.
-
Characterizing stall or output torque in small DC and stepper motors for miniature robotics.
-
Calibration of miniature torque testers and precision instruments like watch mechanisms.
-
Testing holding or starting torque of small motors, servos, and potentiometers.
Tips & Best Practices
-
Ensure correct unit selection when entering values to avoid conversion errors.
-
Use this tool for precise torque values where small magnitudes are critical.
-
Cross-check calibration instruments to maintain accuracy in measurements.
-
Be aware of differences in lever arm units (inch vs centimeter) when interpreting results.
Limitations
-
Both units are non-SI and best suited for very small torque values only.
-
Conversions require care to avoid inaccuracies caused by the small magnitudes.
-
Units reflect torque at different lever arm lengths, so precise conversion is essential.
-
Rounding or approximation errors can impact measurement integrity in sensitive applications.
Frequently Asked Questions
-
What does one ounce-force inch represent?
-
One ounce-force inch is a unit of torque equal to one ounce-force applied perpendicularly at one inch from the pivot, used for very small torque measurements.
-
Why convert ounce-force inch to gram-force centimeter?
-
Converting to gram-force centimeter helps specify very small torques in different unit standards, commonly used in precision calibration and watchmaking.
-
Are these units part of the SI system?
-
No, both ounce-force inch and gram-force centimeter are non-SI units used mainly for measuring small torques.
Key Terminology
-
Ounce-force inch (ozf*in)
-
A unit of torque where one ounce-force is applied at a perpendicular distance of one inch from the pivot, used for measuring very small torque values.
-
Gram-force centimeter (gf·cm)
-
A torque unit equal to the moment produced by a force of one gram-force applied at a distance of one centimeter, commonly used in precision instrumentation.
-
Torque
-
A measure of the rotational force applied to an object causing it to twist or rotate around a pivot.
