20000 milliamp hours to 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.

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.

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. For instance, my iPhone XR has a 2,mAh battery. To figure out its battery capacity in watt hours, we need to know the battery voltage. Most smartphones, including iPhones, use a lithium-ion battery with a nominal voltage of 3. With all the necessary info, we can convert milliamp hours to watt hours by plugging in to the above equation. Most often, converting milliamp hours to watt hours is useful for comparing the battery capacity of batteries with different voltages. The total energy a battery can deliver in watt hours depends on its milliamp hours and voltage. So, if you have batteries with different voltages, looking at their amp hour or milliamp hour capacity alone can be misleading. However, because their voltages are different, we need to calculate their watt hours to be able to accurately compare them. 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. Most electronics and appliances list their energy consumption in watts W , and you can do a quick and dirty estimate of battery runtime by dividing watt hours by watts.

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

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.

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.

If your phone has a battery capacity of 4,mAh, then you can expect to get around 3 phone charges out of your portable charger. Home - Electrical Calculators. Youtube Tiktok Instagram. To estimate how long you'll be able to run your lantern, you first need to calculate the battery's watt hours. In reality, there are a number of factors that affect how long a battery will last. He holds several degrees and certifications. 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 total energy a battery can deliver in watt hours depends on its milliamp hours and voltage. The conversion from electric charge to energy requires the voltage and can be done using the formula below. All Rights Reserved.

Convert milliamp-hours to watt-hours by entering the amount of charge in mAh and the battery terminal voltage below.

It is a measure of the amount of energy being supplied to the load. Hi, I'm Alex. 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. Join Our Telegram Channel Now! To illustrate, let's say you're using a 30,mAh 3. For reference, the average US household uses around 30kWh of electricity per day! The conversion from electric charge to energy requires the voltage and can be done using the formula below. Though, in practice, usable battery capacity varies based on a range of real-world factors including discharge rate and battery age. He holds several degrees and certifications. For example, if a power bank has four Li-ion cells connected in series, it will have an overall voltage of You wouldn't have been able to estimate the runtime had you not converted milliamp hours to watt hours.
