Kilowatt-Hour to Ampere-Hour Converter
How to Convert Kilowatt-hours (kWh) to Ampere-hours (Ah)
To convert Kilowatt-hours (kWh) to Ampere-hours (Ah), use the formula:
kWh to Ah Calculation Formula
The relationship between kilowatt-hours and ampere-hours can be expressed as:
Ah = (kWh × 1000) ÷ VWhere:
- kWh = Kilowatt-hours
- Ah = Ampere-hours
- V = Voltage (in volts)
Example
If you have a total energy consumption of 5 kWh at a voltage of 12V, the calculation would be:
Ah = (5 kWh × 1000) ÷ 12 = 416.67 AhWhat is a Kilowatt-hour (kWh)?
A kilowatt-hour (kWh) is a unit of energy that measures how much electricity is used over time. It represents the energy consumed when one kilowatt (1,000 watts) of power is used for one hour. For example, running a 1,000-watt appliance for one hour uses 1 kWh of energy.
What is an Ampere-hour (Ah)?
An ampere-hour (Ah) is a unit of electric charge that indicates how much current a battery can provide over a specific period. For example, a battery rated at 10 Ah can theoretically provide 10 amps of current for one hour.
The Simple Math Behind the Conversion
To convert kilowatt-hours to ampere-hours, you need to know the voltage of the system. The formula takes into account the voltage to determine how many ampere-hours are equivalent to the given kilowatt-hours. Here’s a breakdown:
- 1 kWh at 12V = 83.33 Ah
- 2 kWh at 12V = 166.67 Ah
- 3 kWh at 24V = 125 Ah
