What is an erg/second?

An erg/second is a CGS unit of power representing one erg of energy transferred per second, commonly used in astrophysics.

Why convert erg/second to milliwatt?

Converting erg/second to milliwatt helps translate older CGS-based data into SI units common in engineering and practical applications.

Can I use this converter for electronic device power ratings?

Yes, converting to milliwatt allows you to interpret power consumption or output of small electronic devices using standard SI units.
