How to convert milliwatts to watts (mW to W)

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

W = mW × 0.001

W = 1 × 0.001

W = 0.001

In other words, 1 milliwatt is equal to 0.001 watts.

Example Conversion

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

  1. Understand the conversion formula: W = mW × 0.001
  2. Substitute the required value. In this case we substitute 7 for mW so the formula becomes: W = 7 × 0.001
  3. Calculate the result using the provided values. In our example the result is: 7 × 0.001 = 0.007 W

In summary, 7 milliwatts is equal to 0.007 watts.

Converting watts to milliwatts

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

mW = W × 1000

m1 = W × 1000

mW = 1000

Or in other words, 1 watt is equal to 1000 milliwatts.

Conversion Unit Definitions

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.

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.
