How is memory capacity commonly measured?

Memory capacity is commonly measured in terms of units that represent the amount of digital information that can be stored. The most prevalent measurements used today are megabytes (MB) and gigabytes (GB). These larger units provide a practical way to express the capacity of modern storage devices such as hard drives, solid-state drives, and memory cards, where capacities can easily reach millions or billions of bytes.

As technology has advanced and storage needs have increased, these higher-level units became necessary for providing better context. For everyday usage, measurements like megabytes and gigabytes give users a clearer understanding of the amount of data they can store or the size of applications and files they commonly work with.

While bits and bytes are fundamental building blocks of digital data, and smaller units like kilobytes (KB) are also relevant, they do not reflect the common scale used for contemporary memory devices. The trend in computing and data storage has increasingly leaned towards using megabytes and gigabytes for measuring capacity, making these units more significant in everyday discussions about memory and storage space.
