Kilowatts
A kilowatt (kW) is equal to 1,000 watts. It is commonly used to express the power output of engines and the power consumption of electrical devices. For example, household appliances and electric vehicles are often rated in kilowatts.
Milliwatts
A milliwatt (mW) is a unit of power equal to one thousandth of a watt. It is often used in contexts where power levels are low, such as in electronics and communications.
