To convert from Megawatt (MW) to Milliwatt (mW), use the following formula:
Let's convert 5 Megawatt (MW) to Milliwatt (mW).
Using the formula:
Therefore, 5 Megawatt (MW) is equal to Milliwatt (mW).
Here are some quick reference conversions from Megawatt (MW) to Milliwatt (mW):

A megawatt (MW) is a unit used to measure power.
It's equal to one million watts.
To put it simply, it's a way to describe a huge amount of electricity being used or generated at a single moment.
One megawatt (1 MW) can power between 750 and 1,000 homes at any given moment.
This number can change depending on what's running in each home (like air conditioning on a hot day).
It's a helpful estimate used by grid operators to understand how much electricity a community needs.
It's easy to mix up megawatts (MW) and megawatt-hours (MWh). Here's a simple way to understand the difference between MW vs. MWh:
So, a power plant has a capacity measured in MW (how much electricity it can make at once).
In contrast, your electricity bill shows your consumption in MWh (how much you actually used over a month).
A megawatt is a tremendous amount of power. To understand its scale, here's a look at the capacity of different power sources:
A milliwatt (mW) is a unit used to measure power.
It is equal to one-thousandth of a watt.
To put it simply, you need 1,000 milliwatts to equal one watt (1 W = 1,000 mW).
The milliwatt (mW) is the perfect unit for measuring the small amount of power used by many common electronic devices.
For example, the power of a Wi-Fi signal, the laser in a Blu-ray player, and the tiny LEDs on your electronics are all measured in milliwatts.
Using such small amounts of power is key to making the batteries last longer in your favorite gadgets, including wireless earbuds, smartwatches, and TV remotes.
While the most common conversion is between milliwatts and watts (1,000 mW = 1 W), some technical fields use a different unit.
In telecommunications and fiber optics, power is often measured in dBm (decibels relative to one milliwatt). This scale makes it easier to work with a vast range of power levels.
For reference, 0 dBm is equal to exactly 1 mW.
When it comes to products with lasers, the milliwatt (mW) rating is a critical safety measure.
To prevent eye injuries, regulatory bodies like the FDA classify lasers based on their power output in milliwatts.
For example, handheld laser pointers sold to the public are legally required in most regions to have a power output of less than 5 mW.
This is a clear example of how milliwatt ratings are used to keep consumers safe.
