What are Watt-hours and Milliampere-hours?

Watt-hours (Wh)

Watt-hours are like a way to measure how much energy a device or a battery can hold or use. Think of them like the energy tanks in a video game. You know how in games, you have a certain amount of energy or power, and as you use it, it goes down?
Well, watt-hours are a way to keep track of that in real life.

For example, if you have a light bulb that uses 60 watts of power and you leave it on for 5 hours, it's like using up 300 watt-hours of energy (60 watts x 5 hours). So, it's like saying, Hey, this light bulb has 300 watt-hours of energy in it.

Milliampere-hours (mAh)

Milliampere-hours are a way to measure how much charge a battery can hold, like the battery in your phone or tablet. Think of this as how much juice your battery has.

Imagine you have a battery with 2000 milliampere-hours (mAh) written on it. That means it can provide 2000 tiny electric currents, called milliamperes, for one hour. It's like saying, This battery can power your device with 2000 tiny electric flows for one hour.

So, in simple terms, watt-hours tell us how much total energy something can hold, like a big energy tank in a game, and milliampere-hours tell us how much juice a battery can give to your devices, like how long your phone can stay powered up before needing to be charged again.

How to Change Watt Hours to Amp Hours (Wh to Ah)

Sometimes, big batteries, like those in cars or special LiFePO4 batteries, like to talk in a language called amp hours (Ah) to tell us how much power they have. It's like they're using their own secret code! But don't worry, we can decode it.

To turn watt hours (Wh) into amp hours (Ah), we just need a simple trick: divide the battery's watt hours by its voltage.

Here's the easy trick: amp hours = watt hours ÷ volts

We can even make it shorter: Ah = Wh ÷ V

Now, let's use this trick in an example: Imagine you have a solar generator, like a super-charged battery, and it has 293Wh written on it. That's like saying it has 293 units of power. Now, look at its secret code, which is 14.4 volts.

So, to find out how many amp hours (Ah) it has, we use our trick: Ah = 293Wh ÷ 14.4V

When we do the math, we find out that this solar generator has about 20.35 amp hours. That's like having 20.35 little energy workers inside, and they can work for one hour before taking a break.

So, in simple terms, we learned how to change the secret code (watt hours) into a language we understand (amp hours) to see how strong our battery is!

Watt-hours to Milliamp-hours Conversion Formula

To convert watt-hours (Wh) into milliampere-hours (mAh), we use a simple formula. Milliampere-hours (mAh) is equal to 1000 times the watt-hours (Wh) divided by the voltage (V) in volts (V):

Here's the formula: Q(mAh) = 1000 × E(Wh) / V(V)

So, in easier terms, milliampere-hours (mAh) can be found by multiplying 1000 with the watt-hours (Wh) and then dividing by the voltage (V):

You can write it like this: milliampere-hours = 1000 × watt-hours / volts

Or, in a shorter way: mAh = 1000 × Wh / V

This formula helps us figure out how much charge (in milliampere-hours) we have when we know the energy (in watt-hours) and the voltage (in volts). It's like a math trick to understand our batteries better!
