Tips & Best Practices
-
Ensure the physical context matches the scaled forces to avoid misinterpretation.
-
Be mindful of computational limitations when handling exceedingly large numerical results.
-
Use this conversion primarily for analytical or comparative purposes across vastly different force scales.
Limitations
-
The conversion involves extremely large numbers, which may cause precision loss in typical computing environments.
-
Practical application requires careful consideration of differing phenomena at planetary and atomic scales.
-
Forces at such differing scales relate to very different experimental and physical conditions.
