The nature of electronics highly involves simplification of certain terms to understand and use them correctly. Measurements and conversion of units is an essential part of electronics.
We are going to dive into something just like that. Conversions are very interesting in electronics. One such is Ampere-Hours (Ah) to Kilowatt-Hours (kWh).
Let’s have a look at how it is done by understanding the Kilowatt Hours.
• What is the Kilowatt Hours?
Before going into the deep briefing of Kilowatt Hours, let’s get familiar with the following basic terms.
We all are familiar with the basic term of ‘kilo’ in the unit system. The SI unit system denotes kilo by its symbolic representation ‘k’. The term is used when any value gets multiplied by thousands (103), which comes from its Greek meaning. The term is commonly used in weighing systems domestically as a prefix unit.
It doesn’t need an introduction as the unit of Power is named after the inventor of the Steam engine – James Watt.
The symbolic representation of Watt is an uppercase W. Watt is an SI derived unit which is an indication of power i.e. rate of work performed in an electrical appliance.
Mathematically represented as
1 W = 1 J/ 1 S
1 W= 1 V x 1 A
The following is a mathematical representation,
1 kWh = 1 kW x 1 h
1 kWh = 3.6 x 106 J
Example – An electrical device with 12 kWh of energy.
Has it ever occurred to you that kilowatt and Kilowatt-hours are one and the same? It has happened to me uncountable times. Let me fill you in that is not the case, they may seem a perfect potato-potahto thing but they are not.
The monthly electricity bills that come are no less than a nightmare. They are the epitome of how these terms work.
Kilowatt means that the rate at which electricity is being used whereas Kilowatt-hour tells you the total consumption of energy in a time period of 1 hr.
For eg, 1 kWh will be described as the amount of energy or electricity used at a constant rate of 1kW.
• Relation and formula for conversion of kWh to Ah
The given below equation will get the Ampere-Hours converted into Kilowatt-hours. By their respective definitions, we know that they give the measure of electric charge and electrical energy respectively.
KWh = (Ah x V) / 1000
With the existence of the above formula, it becomes very easy to convert a given value of Ampere hours (Ah) to Kilowatt hours (kWh).
Follow the given steps for easy conversion –
Ampere-Hours to Kilowatt-Hours conversion are necessary to derive the total energy consumption of a device. To understand electricity, these conversions come handy as electricity ultimately carries energy. That energy is calculated through conversions.
If we understand well about Kilowatt-hours, we may volunteer towards low credit or debit balance. I support this as by paying attention to their definitions we can lower our electricity costs. The bills are supported with measurements in kWh and kW. The former will give the energy consumption readings and the latter about power consumption. If we analyze the rate at which energy is consumed, when and for how long we can do something to reduce it.
If consumption is less, so will be the costs.
