Tips & Best Practices

Understand that the conversion represents a large scale difference and is mostly theoretical.
Use this conversion mainly for modeling and comparative studies rather than practical measurement.
Consider the specific context and particle energy when applying electron cross section values.
Double-check unit selections before converting to ensure accurate results.

Limitations

The vast scale difference means conversions are mostly of theoretical value or modeling use.
Electron cross section values vary based on particle type and energy; one conversion factor is not universally precise.
Direct practical application of this conversion in measurements is rare.
