Frequently Asked Questions
-
What is a milliwatt used for?
-
A milliwatt measures low power levels in electrical, optical, and radio-frequency devices, common in engineering for small components and circuits.
-
Where is erg/second typically applied?
-
Erg/second is used in astrophysics to express luminosities of stars and radiative power, as well as in theoretical calculations relying on the CGS system.
-
How do I convert milliwatts to erg/second?
-
Multiply the power value in milliwatts by 10,000 to get the equivalent erg/second value.
Key Terminology
-
Milliwatt (mW)
-
One thousandth of a watt, used to measure low levels of power commonly in electrical and optical devices.
-
Erg/second (erg/s)
-
A CGS unit of power representing energy transferred per second, mainly used in astrophysics and older scientific contexts.
-
Conversion Rate
-
The numerical factor used to translate a value from one unit to another; here, 1 mW equals 10,000 erg/s.
