To convert from Milliwatt-hour (mWh) to Watt-hour (Wh), use the following formula:
Let's convert 5 Milliwatt-hour (mWh) to Watt-hour (Wh).
Using the formula:
Therefore, 5 Milliwatt-hour (mWh) is equal to Watt-hour (Wh).
Here are some quick reference conversions from Milliwatt-hour (mWh) to Watt-hour (Wh):

A Milliwatt-hour (mWh) is a unit used to measure a small amount of energy.
Think of it like a tiny fuel tank for your electronics. It tells you how much energy a small battery can store and deliver over time.
The official abbreviation you'll see on product specifications is mWh.
You'll most commonly see the mWh rating on the batteries of small, portable gadgets.
It's a direct measure of the battery's energy capacity.
For example, a battery rated at 50 mWh holds more energy than one rated at 30 mWh.
While mWh is practical for consumer electronics, scientists and engineers often use Joules (J), the standard international unit of energy.
The conversion is straightforward and is a key factor in technical calculations.
1 mWh = 3.6 JThis conversion helps engineers compare energy specifications across different standards.
To sum it up, here's what you need to remember about mWh:
Ever looked at the back of a battery pack and felt confused by the numbers? You're not alone!
One of the most important measurements you'll see is the Watt-hour (Wh).
Think of it as the fuel gauge for your electronic devices. This simple guide will break down precisely what a Wh is and why it matters.
A Watt-hour (Wh) is a unit that measures energy. Specifically, it tells you how much energy a device uses over a specific period.
The concept is simple: one Watt-hour is the amount of energy consumed when one watt of power is used for precisely one hour.
A helpful analogy is a car's gas tank. The Watt-hour rating on a battery is like the size of the tank—it tells you the total amount of energy it can store.
The power your device draws (measured in Watts) is like how fast you're driving and using up that gas.
A battery with a higher Wh rating holds more energy and can power your device for longer, just like a larger gas tank lets you drive farther.
You'll find Wh ratings on many of the rechargeable devices you use daily. It's a key indicator of battery capacity and runtime. Some common examples include:
The Watt-hour is directly related to the joule (J), which is the standard scientific unit for energy. The conversion is straightforward:
This is because a watt is defined as one joule per second, and there are 3,600 seconds in an hour (60 seconds × 60 minutes).
A kilowatt-hour (kWh) is simply 1,000 Watt-hours. The prefix "kilo-" means one thousand.
You're probably most familiar with kWh from your home electricity bill. Utility companies use this larger unit to measure your household's monthly energy consumption.
So, when you see that you used 500 kWh last month, it means you used 500,000 Watt-hours of energy.
