How to convert watts to kilowatts (W to kW)

The formula for converting watts to kilowatts is: kW = W × 0.001. To calculate the watt value in kilowatts first substitute the watt value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 watt in kilowatts we follow these steps:

kW = W × 0.001

k1 = W × 0.001

kW = 0.001

In other words, 1 watt is equal to 0.001 kilowatts.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 6 watts to kilowatts is:

  1. Understand the conversion formula: kW = W × 0.001
  2. Substitute the required value. In this case we substitute 6 for W so the formula becomes: k6 = W × 0.001
  3. Calculate the result using the provided values. In our example the result is: 6 × 0.001 = 0.006 kW

In summary, 6 watts is equal to 0.006 kilowatts.

Converting kilowatts to watts

In order to convert the other way around i.e. kilowatts to watts, you would use the following formula: W = kW × 1000. To convert kilowatts to watts first substitute the kilowatt value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilowatt in watts we follow these steps:

W = kW × 1000

W = 1 × 1000

W = 1000

Or in other words, 1 kilowatt is equal to 1000 watts.

Conversion Unit Definitions

What is a Watt?

A watt (W) is a unit of power that measures the rate at which energy is transferred, used, or produced. It represents the amount of energy consumed or generated per unit of time. Here's an example to help illustrate the concept of a watt:
Consider a light bulb with a power rating of 60 watts. This means that the light bulb consumes or emits energy at a rate of 60 joules per second. In simpler terms, it indicates that the light bulb uses 60 watts of power to produce light.
If you were to leave this light bulb turned on for one hour, it would consume a total of 60 watts multiplied by 3600 seconds (the number of seconds in an hour), which equals 216,000 joules or 216 kilojoules of energy. This demonstrates how power consumption, measured in watts, can be related to the total energy usage over a specific time period.
The watt is a fundamental unit of power in the International System of Units (SI) and is widely used in various applications. It provides a common basis for measuring and comparing the power ratings of electrical appliances, devices, machinery, and systems.
In practical terms, wattage is commonly seen on electrical appliances, such as laptops, refrigerators, air conditioners, and electric motors. It helps consumers understand the power requirements or capabilities of these devices and allows for efficient energy management and comparison between different options.
In summary, a watt is a unit of power that represents the rate at which energy is transferred or used. It is denoted by the symbol W. The example of a 60-watt light bulb demonstrates how wattage can be used to quantify power consumption or generation in various electrical devices or systems.

What is a Kilowatt?

A kilowatt (kW) is a unit of power that measures the rate at which energy is transferred, used, or produced. It is equal to 1,000 watts, which means it represents a larger amount of power compared to a single watt. Let's explore an example to better understand a kilowatt:
Imagine you have an air conditioning unit with a power rating of 2 kilowatts. This indicates that the air conditioner consumes or produces energy at a rate of 2,000 watts or 2 kilowatts. In other words, the air conditioner requires 2 kilowatts of power to operate and provide cooling.
If you were to run this air conditioner continuously for one hour, it would consume a total of 2 kilowatts multiplied by 1 hour, which equals 2 kilowatt-hours (kWh) of energy. Kilowatt-hours are a unit of energy that represents the total amount of energy used over a specific period of time. They are commonly used for billing purposes by utility companies.
To put this into perspective, if you use the air conditioner for 10 hours, it would consume a total of 20 kilowatt-hours (kWh) of energy (2 kilowatts multiplied by 10 hours).
Kilowatts are commonly used to describe the power rating or consumption of various appliances, machines, and systems. For example, the power rating of electric vehicles (EVs) is often mentioned in kilowatts, indicating the power output of the electric motor.
In summary, a kilowatt is a unit of power that represents 1,000 watts. It is denoted by the symbol kW. The example of a 2-kilowatt air conditioner demonstrates how kilowatts are used to measure power consumption or generation in various electrical devices and systems, providing a larger scale for power measurement compared to a single watt.
