The term "mebi" refers to a binary prefix used in computing to denote a quantity of 1,048,576 (2^20). It is part of the International System of Units (SI) and is commonly used to describe data sizes, such as memory and storage. The symbol for mebi is MiB, which helps differentiate it from the decimal prefix "mega" that represents 1,000,000 (10^6). Mebi is particularly useful in contexts where binary calculations are more relevant, such as in computer memory. For example, a 1 MiB file is often more accurately described in terms of mebi rather than megabytes, ensuring clarity in data representation and avoiding confusion with decimal-based measurements.
