With the rapid development of the solar power industry in recent years, more and more companies and individuals are getting into solar panel systems with the expectation of using solar power instead of fossil fuel power generation, which not only reduces the environmental pollution and emissions caused by power generation, but also saves the cost of power generation to a large extent. In order to better design and apply your solar panel system, you need to learn numerous things about electrical systems. In this article, we will introduce you to the common units of physical quantities used in electrical systems such as solar panels: milliamps and ampere-hours, and how to convert between the two.
Before learning how to convert, we need to learn about these two related units of measurement.
Milliampere hour is a unit of electricity. To be precise, it is a small unit of electricity converted from the main unit of electricity, the ampere-hour (Ah). Discuss the source of its calculation, is the current in the circuit in milliamps (mA) as a unit of measurement, running time in hours (h) as a unit, multiply the two, you can get the milliampere hours, that is:
A (mA) x T (h) = E (mAh)
The ampere-hour is the primary unit of electricity, or ampere-hour for short. The source of its calculation, is the current in the circuit in amperes (A) as a unit of measurement, running time in hours (h) as a unit, multiply the two, you can get ampere hours, ie:
A (A) x T (h) = E (Ah)
Ampere-hour as the main unit of battery power, its frequency of use is much higher than milliampere-hour. This is especially true in some medium to large electrical systems, such as battery packs for home solar panel systems, etc. However, in some cases, the power of the battery is also measured using milliampere hours, such as the common mobile power of cell phones in our daily life, as well as some smaller batteries.
In general, these two units of measurement of electricity occur in life, in order to facilitate your better understanding of the relevant electrical systems, it is necessary to learn how to convert these two units of measurement.
Learning how to convert from milliampere hours (mAh) to ampere hours (Ah) is easy once you understand the definition and source of calculation of mAh and Ah. First of all, we need to know, milliampere hours and ampere hours belong to the same physical unit of measurement, does not require the introduction of intermediate physical quantities, can be converted directly through the International System of Units in the conversion multiplier, the conversion relationship between the two is as follows:
1mAh=0.001Ah
1Ah=1000mAh
The exact source of the above formula is explained below for you:
In fact, when we studied the source of calculation of milliampere-hour and ampere-hour above, we could find that the difference between the source of calculation of the two lies in the unit of measurement used for the current in that circuit. If the unit of measurement of the current in that circuit is milliamps, multiplying it by time will result in electricity measured in milliampere hours; if the unit of measurement of the current in that circuit is amperes, multiplying it by time will result in electricity measured in ampere hours.
It can be seen that the difference between the two lies between milliamperes and amperes, which are also units of measurement of current, and according to the International System of Units, the conversion relationship between the two is:
1mA=0.001A
1A = 1000mA
The conversion between milliampere-hour and ampere-hour is also 1000, so when you need to convert from mAh to Ah, multiply the value by 1000, and when you need to convert from milliampere to ampere, divide the value by 1000.
First of all, we need to know that current, as an important data used to measure the speed of charge flow in an electric circuit, is commonly measured in amperes, and depending on the magnitude of the order of magnitude, the common ones are: kiloamperes, amperes, and milliamperes. As a result, different orders of magnitude are derived for physical quantities of circuits related to current, such as the ampere-hour and milliampere-hour mentioned in this article, and by the same token, the kiloampere-hour also exists.
It follows that because the unit of measurement of current is constantly changing in circuits of different levels, the units of measurement of other physical quantities need to be changed in order to comply with this change. In order to reduce the number of conversion steps between units of measure, it is especially important to learn how to directly realize ampere-hours and milliampere-hours.
An important component in a solar panel system is the solar array, and in order to improve the power supply capacity of the solar panel system, many families choose to install a matching solar array. For a solar panel, the ampere-hour is an important reference when you buy it, and it is common to perform calculations for milliampere-hour to ampere-hour conversion in the process of purchasing and designing a solar panel. Here’s an example of a 12v Lithium Iron Phosphate solar battery, when the merchant tells you that it provides
15,0000mAh of storage capacity, in order to convert it to amp hours as the unit of measurement, so as to better determine its suitability with your solar panel system, you need to convert it to amp hours by using the above formula, i.e.:
15 0000mAh ÷ 1000 = 150Ah.
