You can not convert Watts (Power) to Ampere-Hours (Amount of charge)!!!

Exept if you know the voltage and the amount of time you use the power.

For example:

If you use P=216 W from a battery of V=12 Volts for t=1 hour, that would be:

Current I=P/V=216/12=18 Amperes

In time of 1 hour, you will take Q=I*t=18 Ampere-Hours from the 12 Volts battery.

What is an Ampere hour?

An ampere hour (A.h) is a non-SI unit of measurement for electrical charge (the SI unit is a coulomb-which is equivalent to an 'ampere second'). So an ampere hour is equivalent to 3600 coulombs.Cells and batteries are generally rated in terms of ampere hours, as a convenient alternative to the kilocoulomb.


How is Ampere-hour calculated if four 65 Ah batteries in series for UPS?

The ampere-hour rating of series connected batteries is the same as that for one battery, so the ampere-hour rating of four 65 Ah batteries in series is still 65 Ah. The reason for this is Kirchoff's current law - the signed sum of the currents entering a node is zero - or - the current at every point in a series circuit is the same.

How do you convert power reading in kWh to kva?

These are two different values. kWh is the amount of kW that are used in an hour. To convert kW to kva use the same formula but leave out the pf (power factor) component.AnswerFirst of all your should realise that power is measured in watts (or kilowatts), not in kilowatt hours! A kilowatt hour is an unit of measurement for energy, or work done, NOT power! So your question doesn't actually make any sense!Furthermore, a kilovolt ampere is the unit of measurement for apparent power, and it should be written as 'kV.A', not 'kva'.So you cannot convert energy in kilowatt hours to apparent power in kilovolt amperes, as we are talking about two completely different quantities! It's like asking "How do you convert miles into kilometres per hour?" That's what I mean by your question not making any sense!The first answer needs correction, as the kilowatt hour is not 'the amount of kilowatts used in one hour'. You do not 'use' kilowatts, as kilowatts is simply a rate. So the correct definition is that a kilowatt hour is the amount of energy used in one hour, at the rate of one kilowatt.

How many amps equal one amp hour?

You can't convert amperes to ampere-hours, for the same reason that you can't (for example) convert kilometers to kilometers per hour, meters to square meters, etc. Those are, quite simply, incompatible units. An ampere is a unit of electrical current; an ampere-hour is really a unit of energy: the energy stored when a current of 1 ampere flows during one hour. To actually be an energy unit, a voltage must be assumed; this is usually 12 volt for a car battery.

How do you get ampere hour from watt hour?

Watt = ampere x volt. So if you know the voltage, you can convert amperes to watts or vice versa. If not, you don't have enough information.AnswerThe ampere hour (A.h) is a unit of measurement for electric charge (the SI unit being a coulomb). The watt hour (W.h) is a unit of measurement for electrical energy (the SI unit being a joule).In the case of cells and batteries, if you multiply its capacity (in ampere hours) by the voltage, then you'll have its capacity in watt hours.

How many amperes a 1.5 ton ac consumes in 1 hour?

I am not sure what you mean, but ampere is a unit of current, not of energy. In the case of a constant current, if the current is 1 ampere in a second, it will be 1 ampere in an hour, or in a day.


How many Ampere Hours in 825 cranking amps?

To convert cranking amps to ampere-hours, you need to know the duration for which the current is drawn. Cranking amps measure the maximum current a battery can deliver for a short duration (typically 30 seconds), while ampere-hours (Ah) represent the total capacity over a longer period (like one hour). Without a specific discharge time, it's not possible to directly convert 825 cranking amps into ampere-hours. Generally, cranking amps are not directly convertible to ampere-hours without additional context on usage.

How much charging ampere required for 200 apmere lead acid battery for ups 12 volt?

To find our what charging ampere to use a simple way is to divide the battery Ampere with its ampere hour (i.e. for car batteries they will say 75ah C/20) this means that the battery has 75 ampere rating based on 20 hour rating... as such to find the charging ampere divide 75 by 20 to get a charging ampere of 3.75... this is for a slow charge - to speed up the charge divide the ampere by 5 hours (to charge the battery from empty to full in 5 hours)...
