Final answer:
1 milliwatt is equivalent to 1 × 10^-3 watts (W) and is commonly used as a reference value for power. A calculator consumes some milliwatts, a computer consumes about 100 watts, and a 100-Watt light bulb consumes 100 watts. The kilowatt (kW) is equal to one thousand (10^3) watts and is commonly used to express the output power of engines and electric devices.
Step-by-step explanation:
1 milliwatt (mW) is a unit of power. The reference value for 1 milliwatt is 1 × 10^-3 watts (W). It is equivalent to 1/1000th of a watt. To put it in perspective, a calculator typically consumes some milliwatts, a computer consumes about 100 watts, and a 100-Watt light bulb consumes 100 watts. The kilowatt (kW) is equal to one thousand watts, and it is commonly used to express the output power of engines and electric devices.
