# Watts to kilowatts

**1 watt in kilowatts: 1 W = 0.001 kW**

kW = W × 0.001

To convert watts to kilowatts, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is kW = W × 0.001. Both units measure power, so the conversion is a fixed factor that never changes.

## Common questions

### How many kilowatts are in one watt?

One watt equals 0.001 kilowatts. kW = W × 0.001.

### How do you convert watts to kilowatts?

Use kW = W × 0.001. So 10 W is 0.01 kW.

### How many watts are in one kilowatt?

One kilowatt equals 1,000 watts, which is the reverse of the conversion above.
