A kilowatt is an SI power unit equal to 1000 watts.
Kilowatts became common as electrical systems and machinery needed a readable scale for larger power values.
kW is used for appliances, generators, motors, EV chargers, HVAC systems, solar arrays, and electrical load planning.
A watt is the SI unit of power equal to one joule per second.
The watt is named after James Watt and became the standard unit for measuring power.
W is used for electronics, appliances, lighting, chargers, motors, power supplies, and detailed electrical calculations.
Mathematically, watt (W) = kilowatt (kW) converted with the formula below.
1 kW = 1,000 W
1 W = 0.001 kW
Formula: value × 1000
Example: 15 kW = 15,000 W
Precision note: Use the exact relationship 1 kW = 1000 W. Round only to match the precision of the source rating or measurement.
1 kW = 1,000 W
1 W = 0.001 kW
