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.

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

20000 milliamp hours to watt hours

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. For example, a 2 mAh of capacity means that the battery can supply a load of 2 milliamperes for one hour before losing all its charge, or it can indicate that the battery can supply a 1 milliampere current to a load for 2 hours. It is a measure of the amount of energy being supplied to the load. The conversion from electric charge to energy requires the voltage and can be done using the formula below. Thus, the energy E in watt-hours is equal to the charge Q in milliamp-hours times the voltage V , divided by 1, Watt-Hours Results:.

Note: You may notice on the battery label that it claims to have 1, watt 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.

Enter the electric charge in milliamp-hours mAh and voltage in volts V and press the Calculate button:. When it comes to understanding electrical power, there are a lot of different terms and measurements to consider. Two of the most common are mAh and Wh. To properly understand the difference between these two units, it's essential to understand what each represents. On the other hand, Wh is a unit of energy used to describe a battery's work.

Note: Like I said, this is a quick and dirty way to estimate battery runtime. Alex Beale Hi, I'm Alex. Now that we know the watt hours of both batteries, we can see that Battery B can deliver nearly 4 times as much energy as Battery A. Phone battery capacities are often given in milliamp hours. New power banks are now available in the market, supporting fast charging and often delivering up to 9 Volts. You know its battery capacity is Ah and its voltage is 12V, so here's how you calculate its watt hours:. For example, a 2 mAh of capacity means that the battery can supply a load of 2 milliamperes for one hour before losing all its charge, or it can indicate that the battery can supply a 1 milliampere current to a load for 2 hours. Our custom-made calculator is designed to convert charge capacity specified in mAh to energy specified in Wh. Calculate Watt Hours. Review Checkmark.

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.

Dmitry Makarov Automation Engineer. It is a measure of the amount of energy being supplied to the load. Thus, the energy E in watt-hours is equal to the charge Q in milliamp-hours times the voltage V , divided by 1, So, in this example, your portable charger has a 12,mAh battery.
