Conversion requires awareness of legacy CGS units and their modern relevance
Frequently Asked Questions
-
What does erg/second measure?
-
Erg/second is a CGS unit of power representing energy transfer of one erg per second, often used in astrophysics and older scientific literature.
-
Why convert erg/second to microjoule/second?
-
Converting erg/second to microjoule/second helps relate legacy power data in CGS units to modern, practical units used in electronics and photonics.
-
What is the conversion factor between erg/second and microjoule/second?
-
1 erg/second equals 0.1 microjoule/second.
