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.

About Calories per Second

One calorie per second (cal/s) = exactly 4.1868 W. It bridges thermochemistry and power: bomb calorimeters and reaction calorimeters characterise exothermic events by cal/s during the reaction interval. Food science uses cal/s to model heat transfer into food during frying or roasting. Since 1 kcal/s = 4,186.8 W, kilocalories per second appear in high-intensity industrial dryers and continuous-flow reactor heat duties. 1 cal/s = 4.1868 W.
