Key Differences
Gigabits and megabits are both units of digital information. A gigabit is a term used to denote a larger amount of digital data compared to a megabit. Specifically, one gigabit is equivalent to 1,000 megabits. When measuring network speeds or data transfer rates, gigabits are often used for faster connections.
Megabits, while smaller than gigabits, are still a common measurement for data. They are especially prevalent in describing slower internet connection speeds. Although gigabits are becoming more standard due to increasing speed requirements, megabits are still widely referenced in many parts of the world.
Gigabit speeds are sought after in modern telecommunications, signifying a higher capacity for data transmission. When an internet service provider offers gigabit speeds, it indicates a more robust and faster service. Conversely, megabit speeds, though adequate for many tasks, represent slower connections.
In the context of storage, both gigabits and megabits are less commonly used, as bytes are the preferred unit. However, when they are used, it’s important to note that one gigabit equals 125 megabytes, and one megabit equals 0.125 megabytes, since there are 8 bits in a byte.
While both gigabits and megabits measure data, their usage varies with technology. Gigabit is increasingly becoming a standard descriptor of network capacity in the era of high-definition streaming and online gaming. Megabit, on the other hand, still maintains relevance for many types of internet activities and service levels.

Gigabit
The gigabit is a multiple of the unit bit for digital information or computer storage. The prefix giga (symbol G) is defined in the International System of Units (SI) as a multiplier of 109 (1 billion, short scale), and therefore.
Megabit
The megabit is a multiple of the unit bit for digital information. The prefix mega (symbol M) is defined in the International System of Units (SI) as a multiplier of 106 (1 million), and therefore 1 megabit = 106bits = 1000000bits = 1000 kilobits.The megabit has the unit symbol Mbit.
