Kilowatts to Watts Calculator
Convert kilowatts to watts and back across the whole SI ladder — milliwatts, watts, kilowatts, megawatts, gigawatts. Every step is a factor of 1,000, and WattSimple names the real equipment that runs at whatever scale your answer lands on.
These are all power units — the rate at which energy moves, right now. Each step is a factor of 1,000: 1 kW = 1,000 W, 1 MW = 1,000 kW. For energy consumed over time — the kilowatt-hours your utility bills — use the kW to kWh converter instead.

What that scale looks like
1,000 W is about a microwave, a toaster, or a space heater.
Typical running draws, not startup surge or nameplate maximums. See the appliance wattage chart for measured figures by appliance.
