What Is kWh to Amps?

Before understanding how to convert kWh to amps, you'll need to learn the meaning of different electrical units like watts, watt-hours, kilowatt-hours, amps, and amp-hours.

Watts measure power based on the rate of the electrical energy that is being dissipated, and watt-hours represent the number of watts discharged over one hour. Kilowatt-hours, often abbreviated as kWh, also measure electrical energy. One kilowatt-hour (kWh) is equal to one thousand watts of power consumed in one hour.

The flow of charge in a circuit or system is called current and is measured in amperes. The term ‘ampere-hour’ determines the electrical charge and often represents the charge capacity of different batteries. One Ah is the amount of electricity charge that's transferred by 1 amp of current in 1 hour.

If you convert kWh to amps, you'll need to know the volts of the circuit. Here is the relationship between kWh and amps, along with an example.

Relation Between kWh and Amps

If you want to convert kWh to Amps, you can use the below formula:

Amps = (kWh × 1000) ÷ (V × H)


kWh = Kilowatt-hour used

V = Voltage of the system

H = Number of hours

Let's say you have an electric device running on a standard 120V circuit for 5 hours. The kilowatt-hour, in this case, is nearly 6kWh.

Amps = (6kWh × 1000) ÷ (120V × 5H) = 10A

Line-to-Line Voltage: Also called line voltage, it is the voltage between any two given phases.

Line-to-Neutral Voltage: Also called phase voltage, it is the voltage between any given phase and neutral.

Jackery Explorer Portable Power Stations have higher watt-hour and ampere-hour ratings. For example, the Jackery Explorer 1000 Plus Portable Power Station has a LiFePO4 battery with a 1264Wh capacity. It has an ampere-hour rating of 30.4Ah and operates at 41.6V. It can charge 99% of low and high-power-consuming appliances for extended periods.

How to Convert kWh to Amps?

If you have the amps, kilowatt-hour, and the number of usage hours of a circuit, you can use the following formula to convert kWh to amps.

how to convert kilowatt hours to amps

Suppose you have a battery with a capacity of 5kWh and operate at 41.6V for 5 hours. The amps can be calculated using the above-mentioned formula.

Amps = (kWh × 1000) ÷ (V × H) = (5kWh × 1000) ÷ (41.6V × 5H) = 24 amps.

How to Convert Amps to kWh?

The formula to convert amps to kWh is given below:

kWh = Amps × Volts × Hours of Use / 1000

how to convert amps to kwh

Let's say you are running a 20 amps electric device on a standard 120V circuit for 4 hours.

Kilowatt-hour = 20A × 120V × 4H / 1000 = 9.6 kWh.

Amps to kWh calculation is helpful when sizing the power station or battery. Since energy usage is generally listed in Wh or kWh, calculating the battery's kilowatt hours will help determine how long the battery can power any device or appliance.

There are many reasons why you would want to convert amps to kilowatt-hours. It can be helpful when comparing batteries or power stations with the same voltage. As the energy usage is generally listed in Wh or kWh on the electricity bills, converting the amps to kWh also reveals how much one appliance contributes to the bill.

How to Convert kWh to Ah?

Converting kWh (electrical energy) to Ah (electrical charge) can be done using the below formula.

Ah = (kWh × 1000) ÷ V

how to convert kwh to ah

That is, the electrical charge in amp-hours equals the energy in kilowatt-hours times 1000, divided by voltage.

Example: Let's convert 6kWh at 120V to Ah.

Ah = (6kWh × 1000) ÷ 120V = 50Ah.

Although both amps and amp-hours measure electrical charge, they are different. Ampere is the rate at which electrons pass through an electrical conductor. In contrast, amp-hours is the charge that moves through the source in one hour.

kWh to Ah conversion is of utmost importance when estimating the battery capacity. Electrical energy is usually measured in kWh, whereas battery capacity is rated in Ah. If you want to determine which battery capacity will meet your electricity needs, you'll need to convert kWh to Ah.

How to Convert Ah to kWh?

If you want to convert Ah to kWh, you'll need to multiply amp hours times volts divided by 1000.

kWh = (Ah × V) ÷ 1000

how to convert ah to kwh

Suppose you want to calculate the kilowatt-hour of the battery. The first step is to locate its amp-hour and voltage, which are often printed on the battery. In this example, we suppose the battery has 100 amp hours and a voltage of 12V.

Kilowatt-hour = (100Ah × 12V) ÷ 1000 = 1.2kWh

Ah to kWh conversion is vital in comparing batteries of different voltages. For example, when we compare a 12V 100Ah battery and a 24V 60Ah, it's better to calculate kWh in each case.

For a 12V 100Ah battery, the kWh will be 1.2kWh. In contrast, for the 24V 60Ah battery, the kWh will be 1.44kWh. That means a 24V 60Ah battery stores more energy compared to 12V 100Ah.

How to Convert Wh to Ah?

In simple words, a watt-hour (Wh) is the energy unit measuring the power capacity (in watts) moving over time (an hour). The number of watts that an appliance uses per hour is the battery life.

An ampere-hour measures the current (in amps) over a period (an hour). It tells you the number of amps a device draws when you are using it for one hour. One important thing to note is that amp-hour isn't a measurement of energy but rather a charge.

If you have the volts (or voltage) of the circuit, you can quickly convert Ah to Wh or vice versa.

how to convert watt hours to amp hours

Suppose you want to know how many amp-hours of current your electrical system can handle, assuming the watt-hours are 100Wh and the voltage is 10V.

Amp-hours = 100Wh ÷ 10V = 10Ah

How to Convert kW to Amps?

Kilowatts is the measure of power, whereas ampere is used to describe current. Since they measure two different units, kW cannot be directly converted to amps. You must know the voltage of the system to execute the conversion.

For any DC circuit, you can convert kW to amps using the below formula.

Amps = 1000 × kW / V

For any single-phase AC circuit, you'll need to keep the power factor in mind.

Amps = 1000 × kW / V × PF

Let's find the current of a 10kW motor with a power factor of 0.8 at 240V.

Amps = 1000 × 10kW / 240V × 0.8 = 52A

Here, the voltage is the RMS value of the applied AC voltage, and PF is the power factor of the load.

For any three-phase AC circuit, you can convert kW to amps if the line-to-line and line-to-neutral voltage are known.

Line-to-Line Voltage:

A = 1000 × kW ÷ (√3 × PF × V)

Line-to-Neutral Voltage:

A = 1000 × kW ÷ (3 × PF × V)

Let's calculate the current of a 30kW three-phase motor with a power factor of 1 and a line-to-line voltage of 240V.

A = 30kW × 1000 ÷ (√3 × 1PF × 240V) = 72 amps

If you want to calculate the amps of 3kW with a line-to-neutral voltage of  60V and 0.8 PF, here's how you can do it.

A = 3kW × 1000 ÷ (3 × 0.8PF × 60V) = 20.8 amps

The main reason to convert kilowatts to amps is by adequately sizing and selecting electrical components.

How to Convert Amps to kW

The simple way to convert amps to kW is by using Watt's Law power formula, which states that I (Amps) = P (Watts) ÷ V (Volts).

The amps to kilowatts conversion formula in the DC circuit is:

Kilowatts = (Amps × Voltage) ÷ 1000

That means the power in kilowatts equals current in amps multiplied by voltage in volts divided by 1000.

Let's say you want to find kilowatts of a circuit with 24 amps of current at 120V.

P (in Kilowatts) = (24A × 120V) ÷ 1000 = 2.88kW

kWh to Amps FAQs

How do you convert kWh per year to amps?

To convert kWh per year into amps, you can use the formula:

Amps = (kWh per year × 1000) ÷ (V × H)

For instance, if you are using an electrical appliance consuming 1000 kWh per year at 120V, then the current draw can be calculated as follows:

Amps = (kWh × 1000) ÷ (V × H) = (1000kWh × 1000) ÷ (120V × 365H) = 22.8A.

Here we assume that the electrical appliance is used for one hour daily.

How many amps hours is 3.6 kWh?

If you have 3.6kWh at 12V, you can convert kWh to Ah using the below formula.

Ah = kWh × 1000 ÷ V = 3.6kWh × 1000 ÷ 12V = 300Ah.

What is the difference between kWh and amp hour?

Kilowatt-hours measure electric power, whereas the ampere-hour represents the electric current. Even though these units measure different things, they are related by the following equation.

Power in Watts = Current in Amps × Voltage

If a battery is rated at 200 amp-hours, it can provide 10A for 20 hours. Multiplying the voltage by the ampere-hour value will help you get the watt-hours value.

In the above equation, the watt-hours will be 100Ah × 12V = 1200Wh. You can divide the result by 1000 to get the kWh value (i.e., 1.2kWh).

What are the relations of amps, watts, and volts?

Amps means the number of electrons flowing through a certain point at any time. Watts is the power or energy an electric appliance consumes. Volts measure the pressure required for an electric current to flow past a wire.

In mathematical terms, watts equals the multiplication of amps and volts.

Relationship between watts, amps, and volts: W = A × V

For instance, if the electric device consumes 10 amps at 12V, the wattage of the appliance will be 10A × 12V = 120W.

Final Thoughts

Kilowatt-hour and amp-hour are critical units for solar systems or electric appliances. You can calculate the compatible solar generator by understanding how much kWh or Wh battery capacity a power station has.

Converting kWh to amps will help you select which power station can supply seamless electricity to your appliances for a long time. Jackery Explorer Portable Power Stations are designed with high Wh and Ah ratings to provide electricity to small and large appliances for a long time.
