Megabyte vs. Gigabyte: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 9, 2024
A megabyte (MB) is a unit of digital information storage equal to 1,024 kilobytes, while a gigabyte (GB) is larger, equal to 1,024 megabytes or about 1 billion bytes.

Key Differences

A megabyte (MB) is a unit of digital data storage, smaller than a gigabyte, representing approximately one million bytes. In contrast, a gigabyte (GB) represents approximately one billion bytes, making it significantly larger than a megabyte.
