About these units
Megabit (Mb)
A megabit equals 1,000,000 bits, a standard networking unit used to express data transfer rates. Internet speeds—both broadband and wireless—are typically quoted in megabits per second (Mbps). Because communication systems often care more about transfer rates than storage quantities, the megabit became a natural standard long before modern high-speed networks. The distinction between megabits (Mb) and megabytes (MB) is crucial, as confusing the two leads to misunderstandings about download times. Megabits remain central to evaluating network performance, streaming quality, and bandwidth provisioning.
Gigabyte (10^9 bytes) (GB (10^9))
A decimal gigabyte is 1,000,000,000 bytes and is the standard unit for hard drive and SSD capacities. As storage technology scaled into the hundreds of gigabytes and then terabytes, the decimal definition became more practical, allowing consistent scaling across consumer and enterprise devices. However, operating systems often report capacities using binary units, causing user confusion (e.g., a "500 GB" drive showing only ~465 "GB"). This mismatch persists despite standardization efforts.
