Multiply by 1,000: 2 kW is 2,000 W.
1 kW is 1,000 W; a 2 kW heater draws 2,000 W while it runs.
For energy cost, convert to watt-hours and divide by 1,000 back to kilowatt-hours.
what it does
One kilowatt is 1,000 watts. Multiply kilowatts by 1,000 and the watts appear, which is what a power figure becomes when it has to match an appliance label or a device rating.
It shows up when a tariff or a solar quote is in kilowatts but a device is rated in watts, when a generator's capacity has to cover appliances listed in watts, when energy monitoring apps switch units mid-graph, and in any calculation that crosses from the bill to the plug.
The shortcut moves the decimal three places right: 1.5 kW is 1,500 W, 0.5 kW is 500 W, 3 kW is 3,000 W. Multiplying by hours turns watts into watt-hours, which is the energy number behind the money.
Type any kilowatt value and the widget answers in watts instantly, with the math on screen. Click to copy, and swap when a watt figure has to be rolled up into kilowatts.
