Tips & Best Practices
-
Ensure you are consistent with the units used in your documentation and tools.
-
Use the conversion in environments where standard gravity applies for best accuracy.
-
Double-check calibration tools and torque testers to confirm unit compatibility.
-
Refer to legacy datasheets carefully to decide when gravitational units are required.
-
Apply this conversion when dealing with very small torque values to maintain precision.
Limitations
-
This conversion assumes a constant standard gravity value; deviations can impact accuracy.
-
Unit conventions and legacy usage may differ, requiring careful unit consistency checks.
-
Conversion formulas do not cover larger torque units beyond the small torque range.
