Electric power

img Electric power is the transfer of electrical energy within a circuit. Its SI unit is the watt, the general unit of power, defined as one joule per second. Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.

Watt hours - Wh
mAh = miliamps hours

How to convert mAh into Wh (Watt Hours)

While mAh only suggests "two dimensions" of capacity, Wh is a solid "three dimensions" figure that calculates battery capacity as a whole.

Ah * V = Wh

You may not have heard of AH before.

Don't feel stressed about another unknown terminology.

Ah is just a different unit that is equal to 1000mAh

For a 3.7V 2600mAh battery, the Wh will be:

2600mAh * 3.7V

2.6 Ah * 3.7V = 9.62 Wh

So now we know the energy of a 3.7V 2600mAh battery is 9.62Wh.
