How do you convert watt to watthour?

Answer 1

You cannot, unless your first "h" (in amph), is a msitake. If you really mean, convert Whr into Ahr, then you need to divide the Whr figure by the voltage.

AnswerYou don't! A watt hour measures energy, whereas an ampere hour measures charge -two different quantities!

Answer 2

It's unfortunate that both of these units include the same word "watt". That gives the impression

that one can be converted into the other.

These two units are used for measuring different quantities. They have different physical dimensions,

and neither one can be converted to the other. (One hint that this is so is the fact that they have

different names.)

The "watt" is a unit of power. It measures how fast energy is being transferred. It's equal to

one joule of energy per second.

The "watt-hour" is a unit of energy. It's equal to the amount of energy transferred in an hour

at the rate of one joule per second. So it's equal to 3,600 joules of energy.

The rate at which energy is transferred can't be converted into the amount of energy that's

transferred, just as the speed of your car can't be converted into the distance you drive.

Answer 3

The conversion factor for J to Wh is 0.000278: J x 0.000278 = Wh

Answer 4

Watt-hours are converted to amp-hours the same as converting watts to amps. You divide the watts by the voltage and the answer is the amps.

Answer 5

Multiply the power you used (in watts) by the length of time you used it (in hours)

to get the number of watt-hours of energy you used.

Answer 6

A Watt measures power, while a Unit measures energy. A Unit of energy is 1 kilowatt-hour, which is 1000 watts for 3600 seconds, or 3.6 million Joules.
