Kilowatt-Hour (kWh)=1000Voltage (V)×Capacity (Ah) Suppose you have a battery with a voltage of 12 volts and a capacity of 50 ampere-hours.
To convert kWh to Ah, divide the kilowatt hours by the voltage (V). The formula is Ah = kWh / V. For example, if you have a 5 kWh battery with a voltage of 12V, the calculation would be 5 kWh / 12V = 0.4167 Ah. Use our kilowatt hours to amp hours conversion calculator for easy and accurate conversions at different voltage levels.
Conversion formula: amp hours = kilowatt hours ÷ volts × 1000 Abbreviated: Ah = kWh ÷ V × 1000 Let's say you own a solar generator with a battery capacity of 2.16 kilowatt hours. You look through the product manual and find that the battery voltage is 43.2 volts. Knowing these two numbers, you can now calculate your battery capacity in amp hours.
For example, if a battery has a capacity of 100 Ah at 12V, the conversion would be: kWh = (100 Ah × 12V) / 1,000 = 1.2 kWh. This means the battery can provide 1.2 kilowatt-hours of energy when fully charged. See also How to Measure Amperage?
One Ah is the amount of electrical charge transferred by one amp of current in one hour of time. Kilowatt-hours, expressed as kWh or kW·h, are used to measure electrical energy. One kWh is equal to one kilowatt, or one thousand watts, of power consumed for one hour of time.
Let's say your phone's battery has a capacity of 3500 milliamp hours and a voltage of 3.7 volts. Here's how to calculate its capacity in kilowatt hours: Your phone battery has a capacity of 0.01295 kilowatt hours, or 12.95 watt hours.

Nissan Leafs, which have under 200 miles of range, come in 40 kWh and 60 kWh variants. The Long Range Tesla Model 3, capable of over 300 miles of range, comes with a 75 kWh battery pack.
While the basic formula for kWh remains consistent (kWh = Voltage x Current x Time), the specific methods for calculating kWh may vary for different battery types. Lead-acid
Kilo means 1,000, so a kilowatt is 1,000 watts, but what about kWh, or kilowatt-hours? The difference between a kilowatt and a kilowatt hour is that a kWh measures energy consumption over time. A 100 W light bulb is 0.1 kW. So if the light is on for an hour, it would consume 0.1 kWh. If it is left on for 10 hours, it would consume 1 kWh.
To calculate KWH, divide that wattage by 1000, then multiply by the total time in hours. What is KWH? KWH is short for kilowatt hour, which is a unit of measure of energy that is equal to 3.6 megajoules. More simply the kilowatt-hour is a measure of energy consumed or produced by one kilowatt sustained over 1 hour.
