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 SI unit for measuring power output and consumption.
W is used for electronics, appliances, lighting, chargers, motors, power supplies, and electrical load ratings.
A kilowatt is an SI power unit equal to 1000 watts.
Kilowatts became common as electrical equipment and utility systems needed a readable scale for larger power values.
kW is used for appliances, generators, motors, solar systems, EV chargers, HVAC equipment, and electrical load planning.
Mathematically, kilowatt (kW) = watt (W) converted with the formula below.
1 W = 0.001 kW
1 kW = 1,000 W
Formula: value × 0.001
Example: 15 W = 0.015 kW
Precision note: Use the exact relationship 1000 W = 1 kW. Round the final result based on the precision of the device rating or load estimate.
1 W = 0.001 kW
1 kW = 1,000 W
| Watt [W] | Kilowatt [kW] |
|---|---|
| 0.01 W | 0.00001 kW |
| 0.1 W | 0.0001 kW |
| 1 W | 0.001 kW |
| 2 W | 0.002 kW |
| 5 W | 0.005 kW |
| 10 W | 0.01 kW |
| 20 W | 0.02 kW |
| 50 W | 0.05 kW |
| 100 W | 0.1 kW |
One watt equals 0.001 kilowatts.
1500 W equals 1.5 kW.
Yes. Kilo means one thousand, so the relationship between watts and kilowatts is exact.
