How to Convert Megabits to Gigabits
To convert megabits to gigabits, divide by 1,000. This gives you the equivalent storage size in the target unit. Related: Gb to Mb calculator.
Mb: A megabit is 1,000 kilobits or 1,000,000 bits. Standard unit for internet connection speeds. You might also need: Mb to ZiB converter.
Gb: A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. See also: b to Gb.
1 Mb = 0.001 Gb (using SI decimal standard) — or equivalently, 1 Gb = 1,000Mb.
Mb to Gb Conversion Formula
// Convert Mb to Gb
Gb = Mb × 0.001
// Reverse: Convert Gb to Mb
Mb = Gb × 1,000
Mb to Gb Conversion Examples
100 Mb = 0.1 Gb
256 Mb = 0.256 Gb
500 Mb = 0.5 Gb
1,000 Mb = 1 Gb
2,048 Mb = 2.048 Gb
What Is a Megabit?
A megabit is 1,000 kilobits or 1,000,000 bits. Standard unit for internet connection speeds. Use our Gibibytes in Mebibytes.
The megabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: converting Terabits Per Second to Gigabytes Per Second.
Common uses: Internet speeds (Mbps), video streaming bitrates, network bandwidth See also: Mb to YB conversion rate.
1 Mb = 1 × 10⁶ bits = 125,000 bytes.
The megabit can be abbreviated as Mb; for example, 1 megabit can be written as 1 Mb.
What Is a Gigabit?
A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. Use our calculate YB to Gb.
The gigabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: how many Kibibytes in a Yib.
Common uses: Fiber internet speeds, enterprise networking, 10GbE connections Learn more: how many Tibps in Tebibytes Per Second.
1 Gb = 1 × 10⁹ bits = 125 × 10⁶ bytes.
The gigabit can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.

💡 Storage Engineer Tip
For accurate capacity planning, always verify whether specifications use SI decimal (base 1000) or binary (base 1024) units. The difference becomes significant at larger scales.
