About watts and kilowatts
The Conversion Formula
To convert watts to kilowatts, multiply the value by the conversion factor: 1 W = 0.001 kW. For a worked example, suppose you need to convert 25 W to kilowatts: 25 × 0.001 = 0.025 kW. To convert in the opposite direction, divide by 0.001, or equivalently multiply by 1000.
About watts
The Watt (W) is the SI unit of power, equivalent to one Joule per second. It is named after James Watt, the inventor of the modern steam engine. It is the standard for measuring electrical power worldwide, from LED bulbs to supercomputers. watts are commonly used in Light bulbs, Electronics, Speakers, and Scientific data, Cycling (power output).
A typical LED bulb uses about 9 Watts.
About kilowatts
The kilowatt (kW) is the most common unit for rating home appliances and electric motors. In many countries (like Australia and Germany), car engine power is officially rated in kilowatts, not horsepower. It is also the unit used to rate the charging speed of electric vehicles. kilowatts are commonly used in EV charging stations, Home appliances (Microwaves), Generators, and Car engines (Metric), Electric heaters.
A microwave uses about 1 kilowatt.
When Would You Convert watts to kilowatts?
Converting between watts and kilowatts is one of the most common power conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 W = 0.001 kW) memorized or bookmarked can save time in professional and everyday contexts alike.
