To convert from electrical charge to energy use the formula below along with the voltage. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on. The key is to use the watts you know to calculate the amps at the battery voltage.

Here is a nifty amp-hour calculator that converts watt. The electrical charge in amp-hours is equal to the energy in kilowatt-hours times 1000 then divided by the voltage. It is possible to convert watt-hours to amp-hours using the following formula.

50Ah x 24V 1200Wh. Refer this link for more information on how to size a battery bank for solar photovoltaic panels or. For example say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours.

In the chart above it says that 20 amp. How to Convert Amps Into Kilowatt Hours. Earn 10 reputation not counting the association bonus in order to answer this question.

For example if you have a 2 Ah battery rated at 5 Volts that lasts for 2 hours the wattage is 2Ah 5V 2h 5W. Therefore a 100ah amp hour battery will last for 1000 hoursA slightly different example is a 60 watt fridge running on a 12 volt power source uses 60 12 5 amps but only while the motor runs. To calculate amp-hours from watt-hours we need to rearrange this equation to.

DC watts to amps calculation. Amp-hours Watt-hours Volts. However it is highly recommended not to discharge.

Amperes to kW equivalence table conversion and transformation Fp 08 voltage 220V AC 3F. If you have. A very small user of power is a 12 watt LED light running on a 12 volt power source will use 12W 12V 01 amps.

If we simplify and assumed a linear drop in voltage over time far from reality the average voltage would be 211672 189 V. For example lets convert 5 kWh at 120 V to Ah. Milliamp hours mAh Watt hours Wh 1000 Volts V.

Ah 5000 120 V. To showcase how amp-hours does not equal energy you could get the same 1200 watt-hours from a 24V battery. A single ampere represents a single coulomb of electrical charge which passes throughout every part of the conducting item within a second.

Convert Amp hour to Watt hour Ah to Wh Insert the Amp hours Ah and voltage V below and click on Calculate to obtain Watt hours Wh. If for example you consume 100 kwh in a day at 240VAC and assume a steady state load thats 100 kwh divided by 24 hours or a 417 kw load. The phase current I in amps A is equal to the power P in watts W divided by the power factor PF times the RMS voltage V in volts V.

For the watt-hour to amp-hour conversion you also need voltage V. For example if you have a 2 Ah battery rated at 5 V the power is 2Ah 5V 10Wh. The electrical energy in kilowatt-hours is equal to the charge in amp-hours times the voltage then.
