What are watts and kilowatts?
The watt is the SI unit of power, one joule per second. A kilowatt is 1,000 watts, used for appliances, motors, and EV charging. For reference: a typical car engine makes 100–150 kW (about 134–201 hp).
How to convert watts to kilowatts
1 W = 0.001 kW. To convert, multiply the number of watts by 0.001. For example, 5 W = 0.005 kW, and 20 W = 0.02 kW. To go the other way, multiply kilowatts by 1,000 (since 1 kW = 1,000 W).
