20000 milliamp hours to watt hours

Or would you rather convert watt hours to milliamp hours? Here's a chart converting milliamp hours to watt hours at 3. Phone battery capacities are often given in milliamp hours.

Our custom-made calculator is designed to convert charge capacity specified in mAh to energy specified in Wh. A battery with a higher mAh value will power a system for a longer time. It is typically used to specify and describe the total amount of energy retained by a battery. Wh is calculated from the voltage V provided by a battery, multiplied by the current amps supplied by a battery for a certain time usually in hours. Generally, we use mAh for cells and batteries, whereas watt-hours for energy storage systems. We must consider another variable, the Volt, for calculating the power capacity denoted by Wh. Volt refers to the difference in the electric potential between the positive and negative terminals of a battery.

Home - Electrical Calculators. The mAh to Wh calculator is a simbple tool that allows you to convert charge in milliamp-hours mAh to energy in watt-hours Wh with just a few clicks. The calculator will instantly provide you with the energy result in watt-hours. This calculator is particularly useful for those working with batteries or other energy storage devices and need to know the energy output in watt-hours. The energy E Wh in watt-hours is equal to the electric charge Q mAh in milliamp-hours times the voltage V V in volts V divided by An example of mAh to Wh conversion could be calculating the energy capacity of a portable phone charger. To convert mAh to Wh, we can use the following formula:. Therefore, the portable phone charger has an energy capacity of 50 Wh, which can be used to charge a smartphone or other devices. Never miss out on the latest updates, exclusive content, and special offers. Enter charge in milliamp-hours: Enter voltage in volts: Calculate Reset. Join Our Telegram Channel Now! About The Author. Dmitry Makarov Automation Engineer. Electrical Engineer.

The total energy a battery can deliver in watt hours depends on its milliamp hours and voltage. Most electronics and appliances list their energy consumption in watts Wand you can do a quick and dirty estimate of battery runtime by dividing watt hours by watts. The form has been submitted successfully!

Convert milliamp-hours to watt-hours by entering the amount of charge in mAh and the battery terminal voltage below. Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications. Full bio. Units like milliampere-hours mAh and watt-hours Wh are commonly used to describe the battery capacity. While it is impossible to measure the internal characteristics of a battery because it is a closed system, we can use the parameters observable at the battery terminals to estimate the internal measures like stored charge and total energy capacity. The milliampere-hour capacity of a battery describes the duration for which a battery can supply one milliampere of current and the maximum amount of current it can supply for an hour.

Welcome to our watt-hour calculator , which allows you to convert electric charge in milliamp hours to watt-hours expressing the electrical energy transfer power of the system. You can also calculate watt-hours by entering the power of the device and the time period in hours directly. This quick and intuitive watt-hour calculator is a tool that allows you to convert electric charge in milliamp or amp hours to watt-hours describing energy. If you want to further convert watt-hours to joules , you can also try another of our calculators, namely the energy conversion calculator. Our watt hour calculator allows you to use electric charge in milliamp or amp hours and voltage in volts to calculate the energy in watt-hours or joules. Amp hours — the shortened name of ampere-hour — indicates how much charge can flow through a battery per one hour. More specifically, it is an electric charge in a battery that enables 1 ampere of current to flow for one hour. For standard AA or AAA batteries, you do not need to use amp hours, as their rating is provided in milliampere-hours mAh. On the other hand, voltage is expressed in volts V and describes the "pressure" that causes electricity to flow within a circuit.

Though, in practice, usable battery capacity varies based on a range of real-world factors including discharge rate and battery age. These examples work for most power banks, smartphones, and similar devices which generally come with 3. Our custom-made calculator is designed to convert charge capacity specified in mAh to energy specified in Wh. You look in the product manual and see that the battery voltage is 3. Hopefully, now you understand better the relation between mAh and Wh and can confidently make the conversion. For reference, the average US household uses around 30kWh of electricity per day! So, in this example, your portable charger has a 12,mAh battery. The conversion from electric charge to energy requires the voltage and can be done using the formula below. To illustrate, let's say you're using a 30,mAh 3. He lives in Tennessee. To estimate how long you'll be able to run your lantern, you first need to calculate the battery's watt hours.
