Megabits (Mb) to Gigabits (Gb) Converter
Type your storage value in the input field to find Gigabits (Gb) equivalent of your Megabit (Mb) value. 1 Mb = 0.001 Gb, calculated across both decimal (SI) and binary (IEC) standards.

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
Megabit to Gigabit 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

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.
