Limitations

The erg represents very small energy amounts, making converted numerical values very small and possibly less readable.
Precision may be affected due to the significant magnitude difference between erg and kilojoule units.
The erg unit is primarily historical or limited to CGS contexts; it is not commonly used in modern industrial applications.
Conversions should consider appropriate rounding or significant figures to maintain meaningful results.
