Conversion Formula

mW = erg/s × 1.000000000e-4

About Ergs per Second

An erg per second (erg/s) is the CGS unit of power - exactly 10⁻⁷ W. Despite SI adoption, erg/s persists in astrophysics: the Sun's total luminosity is 3.828 × 10³³ erg/s; a peak supernova radiates ~10⁴³ erg/s - more power than the Sun emits over its 10-billion-year lifetime. X-ray binaries, active galactic nuclei, and neutron star accretion rates are catalogued in erg/s across decades of archival literature. 1 erg/s = 10⁻⁷ W.

About Milliwatts

A milliwatt (mW) is 10⁻³ W - the power scale of consumer wireless communications. Wi-Fi access points transmit at 100 mW (20 dBm); mobile phones peak at up to 1,000 mW. A laser pointer emits 1-5 mW; an LED indicator 10 mW; Bluetooth Classic peaks at 100 mW. Standby power implications: 1 mW × 10⁹ devices × 1 year = 8,760 MWh - enough to power a small town, underscoring why milliwatt standby matters at scale. 1 mW = 10⁻³ W.
