How to convert kilowatts to milliwatts (kW to mW)

The formula for converting kilowatts to milliwatts is: mW = kW × 1000000. To calculate the kilowatt value in milliwatts first substitute the kilowatt value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 kilowatt in milliwatts we follow these steps:

mW = kW × 1000000

mW = 1 × 1000000

mW = 1000000

In other words, 1 kilowatt is equal to 1000000 milliwatts.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 7 kilowatts to milliwatts is:

Understand the conversion formula: mW = kW × 1000000
Substitute the required value. In this case we substitute 7 for kW so the formula becomes: mW = 7 × 1000000
Calculate the result using the provided values. In our example the result is: 7 × 1000000 = 7000000 mW

In summary, 7 kilowatts is equal to 7000000 milliwatts.

Converting milliwatts to kilowatts

In order to convert the other way around i.e. milliwatts to kilowatts, you would use the following formula: kW = mW × 0.000001. To convert milliwatts to kilowatts first substitute the milliwatt value into the above formula, and then execute the calculation. If we wanted to calculate 1 milliwatt in kilowatts we follow these steps:

kW = mW × 0.000001

kW = 1 × 0.000001

kW = 0.000001

Or in other words, 1 milliwatt is equal to 0.000001 kilowatts.

Conversion Unit Definitions

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.

What is a Milliwatt?

A milliwatt (mW) is a unit of power that measures the rate at which energy is transferred or work is done. It is equal to one thousandth (1/1000) of a watt. To understand the concept of a milliwatt, let's consider an example:

Imagine you have a small flashlight that consumes 10 milliwatts of power. This means that the flashlight uses energy at a rate of 10 milliwatts to produce light. In other words, it requires 10 thousandths of a watt to operate.

To put this into perspective, if you were to use the flashlight continuously for one hour, it would consume 10 milliwatts (or 0.01 watts) of power per hour. This measurement is commonly used to describe the power consumption of small electronic devices, low-power LED lights, and other energy-efficient devices.

The milliwatt is particularly useful when dealing with low-power applications or when precise measurements of small amounts of power are required. It helps quantify power levels in a more manageable and granular manner.

In summary, a milliwatt is a unit of power that represents one thousandth of a watt. It is commonly used to measure low-power devices and is denoted by the symbol mW. The example of a flashlight consuming 10 milliwatts demonstrates how this unit is used to quantify power consumption or energy transfer in various electronic devices.
