1 Wh = ? Mah: Understanding the Conversion
When it comes to measuring the energy capacity of batteries, two common units of measurement are Watt-hours (Wh) and Milliampere-hours (mAh). While they are related, they are not directly interchangeable. In this article, we'll explore the conversion between Wh and mAh, specifically focusing on the relationship between 1 Wh and mAh.
What is a Watt-hour (Wh)?
A Watt-hour (Wh) is a unit of energy that represents the amount of work done by a power source, typically a battery, over a period of time. It is calculated by multiplying the power in watts (W) by the time in hours (h). In other words, Wh measures the total amount of energy stored in a battery.
What is a Milliampere-hour (mAh)?
A Milliampere-hour (mAh) is a unit of measurement for the capacity of a battery. It represents the amount of electric charge a battery can deliver in one hour. mAh is commonly used to express the capacity of small batteries, such as those used in portable electronics.
Converting Wh to mAh
To convert Wh to mAh, we need to know the voltage of the battery. The formula to convert Wh to mAh is:
mAh = (Wh * 1000) / Voltage
Let's use an example to illustrate this conversion. Suppose we have a battery with a capacity of 1 Wh and a voltage of 3.7V. To convert this to mAh, we would use the formula as follows:
mAh = (1 Wh * 1000) / 3.7V mAh ≈ 270 mAh
So, in this case, 1 Wh is approximately equal to 270 mAh.
Conclusion
In conclusion, while Wh and mAh are related units of measurement, they are not directly equivalent. To convert between the two, we need to know the voltage of the battery. By understanding the conversion between Wh and mAh, we can better appreciate the energy capacity of batteries and make more informed decisions when selecting batteries for our devices.
