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.

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.

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. 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. It is the force required to overcome the resistance and move the electrons to make the battery work. The voltage of a power bank depends upon the battery cells used and can fluctuate between brands and models. However, generally speaking, the battery cells in power banks are either Li-Poly or Li-Ion , both of which are 3. This is why all power banks come with a step-up voltage converter to produce the 5 Volts required for charging an external device. New power banks are now available in the market, supporting fast charging and often delivering up to 9 Volts. Most of the power banks have battery cells internally connected in series to achieve the required voltage. For example, if a power bank has four Li-ion cells connected in series, it will have an overall voltage of

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:.

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.

20000 milliamp hours to watt hours

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. Essentially, mAh tells you how long a battery can last, while Wh tells you how much power it can supply. Calculating the Conversion between these two units can be tricky. Still, it's an important step to take if you want to accurately compare different battery types and make informed decisions about your power needs. In this formula, V represents the voltage of the battery. For example, if you have a mAh battery with a voltage of 3.

During that time, he's built Footprint Hero to over 7 million blog visits and 18 million YouTube views. Youtube Tiktok Instagram. You look in the product manual and see that the battery voltage is 3. It is a measure of the amount of energy being supplied to the load. Units like milliampere-hours mAh and watt-hours Wh are commonly used to describe the battery capacity. A battery with a higher mAh value will power a system for a longer time. Learn how we calculated this below scroll down. 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. Note: You may notice on the battery label that it claims to have 1, watt hours. Dmitry Makarov Automation Engineer. Or would you rather convert watt hours to milliamp hours? Home - Electrical Calculators. Now that you know its watt hours, you can estimate its runtime by doing the following calculation:.

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.

These examples work for most power banks, smartphones, and similar devices which generally come with 3. You know its battery capacity is Ah and its voltage is 12V, so here's how you calculate its watt hours:. Author of scientific publications. If you want to know the capacity of your battery or portable charger the other way around, here are some common values:. It is typically used to specify and describe the total amount of energy retained by a battery. Calculate Reset. By Joe Sexton. To convert mAh to Wh, we can use the following formula:.
