How to Convert Watts to Kilowatts
A watt (W) is the standard SI derived unit of power. A kilowatt (kW) is exactly equal to 1,000 watts. This means that to convert from smaller units (Watts) to larger units (Kilowatts), you must divide by 1,000.
The Conversion Formula
To convert any value in watts to kilowatts, divide the watt figure by 1,000.
- Formula:
Kilowatts (kW) = Watts (W) / 1000 - Example: If you have an appliance like a microwave drawing 1,200 Watts, you divide 1,200 by 1,000 to get exactly 1.2 kW.
Common Watts to kW Conversions
| Watts (W) | Kilowatts (kW) |

| 500 W | 0.5 kW |
| 1,000 W | 1 kW |
| 1,500 W | 1.5 kW |
| 2,000 W | 2 kW |
| 5,000 W | 5 kW |
Frequently Asked Questions
How do I find how many Watts an appliance uses?
Most electrical appliances have a small compliance sticker (usually on the back, bottom, or near the power cord inside) that lists the exact wattage (e.g., "1200W"). You can input that number here to get the Kilowatt rating.
Why is converting to kW important for my electricity bill?
Utility companies bill you based on Kilowatt-Hours (kWh), not Watt-Hours. To figure out how much an appliance costs to run, you first must convert its power draw from Watts to Kilowatts, and then multiply by the hours it ran.
Is converting Watts to kW the same as converting Grams to Kilograms?
Yes, the mathematical principle is completely identical. The prefix 'kilo' always means 1,000 of the base unit. You are simply dividing by 1,000.
