How to Convert Amp-Hours to Kilowatt-Hours?

Amp-hours (Ah) is a unit of electric charge commonly used to measure the capacity of a battery. It represents the amount of electrical energy a battery can store and deliver over time. One ampere-hour equals a current of one ampere flowing for one hour.

Kilowatt-hours (kWh) is a unit of energy commonly used to measure electricity consumption or production over time. It measures the amount of energy used or generated by an electrical device or system with a power rating of one kilowatt (kW) over one hour.

Kilowatt-hours are commonly used on electricity bills to measure and charge for the amount of energy consumed by households, businesses, or other entities. It’s also used in renewable energy systems to quantify the amount of electricity generated by solar panels, wind turbines, and other sources over a specific period.

To convert from capacity of batteries to energy, the formula could convert Ah to kWh:

Formula: Kilowatt-Hours = Amp-Hours × Volts ÷ 1000

Abbreviated Formula: kWh = Ah × V ÷ 1000

For example, if we want to convert 100Ah at 24V to kWh, energy in kWh is 100Ah×24v÷1000 = 2.4kWh.
