Millicowatthours

Millicowatthours, abbreviated as mWh, is a unit of energy. It is derived from the standard SI unit of energy, the joule, and is a subdivision of the watthour. One watthour represents the energy consumed or produced by a device with a power of one watt operating for one hour. A millicowatthour is one-thousandth of a watthour. Therefore, 1 Wh = 1000 mWh. This unit is particularly useful for measuring very small amounts of energy, such as those consumed by low-power electronic devices or batteries. For instance, a small sensor or a microcontroller might consume energy measured in millicowatthours over a period of time. Similarly, the capacity of very small batteries, like those found in wearable electronics or tiny medical implants, might be expressed in millicowatthours, indicating the total energy they can store and deliver. While the kilowatt-hour (kWh) is commonly used for household electricity consumption, the millicowatthour serves the opposite end of the energy measurement spectrum, catering to micro-energy applications. It facilitates a more precise and manageable representation of energy in contexts where larger units would result in unwieldy decimal numbers.
