Kilowatts to Watts Converter

Enter the power in kilowatts below to convert it to watts.

Result in Watts:

1 kW = 1,000 W

How to Convert Kilowatts to Watts

To convert a measurement in kilowatts to a measurement in watts, multiply the power by the following conversion ratio: 1,000 watts/kilowatt.

Since one kilowatt is equal to 1,000 watts, you can use this simple formula to convert:

watts = kilowatts × 1,000

The power in watts is equal to the power in kilowatts multiplied by 1,000.

For example, here's how to convert 5 kilowatts to watts using the formula above.

watts = (5 kW × 1,000) = 5,000 W

How Many Watts Are in a Kilowatt?

There are 1,000 watts in a kilowatt, which is why we use this value in the formula above.

1 kW = 1,000 W

Kilowatts and watts are both units used to measure power. Keep reading to learn more about each unit of measure.

What Is a Kilowatt?

One kilowatt is the power equal to 1,000 watts, or the energy consumption at a rate of 1,000 joules per second.

The kilowatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "kilo" is the prefix for thousands, or 10³. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.

What Is a Watt?

One watt is the power equal to the rate of energy of one joule per second in an electrical circuit.^[1] One watt is also equal to the power produced in a circuit with a voltage potential of one volt with a current of one amp.

The watt is the SI derived unit for power in the metric system. Watts can be abbreviated as W; for example, 1 watt can be written as 1 W.

Watt's Law states the relationship between power, current, and voltage. Using Watt's Law, it's possible to express the power in watts as an expression using current and voltage.

P_W = I_A × V_V

The power in watts is equal to the current in amperes times the potential difference in volts.

Combining this with Ohm's Law, it's also possible to express the power in watts using resistance in addition to volts and amps.
