1 Gbit/s equals 125 MB/s. To convert Gbit/s to MB/s, multiply the value by 125; divide by 125 to convert back. Enter any number above and the result appears instantly — free and entirely in your browser.
How do you convert Gbit/s to MB/s?
The conversion formula is MB/s = Gbit/s × 125. The conversion factor is fixed by definition, so the result is always exact.

What is Gbit/s (Gbit/s)?
A gigabit per second (Gbit/s) is 1,000 Mbit/s. Gigabit Ethernet and fibre plans use it; a full 1 Gbit/s carries at most 125 MB/s — one gigabyte in eight seconds.
What is MB/s (MB/s)?
Megabytes per second (MB/s) is what a download window shows. One MB/s equals 8 Mbit/s, so a 50 Mbit/s line tops out at about 6.25 MB/s before any protocol overhead.
Why convert Gbit/s to MB/s?
Internet plans are sold in megabits per second, downloads run in megabytes per second, and the factor of eight between them is the most common misunderstanding in the whole field. Storage tools add a second gap by counting in binary units (MiB/s).
Eight bits make one byte, so a 100 Mbit/s line carries at most 12.5 MB/s. EU Regulation 2015/2120 obliges fixed-line providers to state the minimum, normally available and maximum speed in the contract — the advertised figure is a ceiling, not a promise.
What can the converter not tell you?
This converter changes units, nothing else. It cannot tell you how fast a file will actually arrive: protocol overhead, Wi-Fi, the server at the other end and everyone else on the line all cost throughput, and a plan states the line rate, not the delivered rate. Only a measurement answers that question.
How to convert Gbit/s to MB/s
- Enter the value in Gbit/s into the left field of the converter.
- Read the result in MB/s instantly in the right field — it updates automatically.
- Use the swap button to reverse the direction (MB/s to Gbit/s).
The converter runs entirely in your browser: no uploads, no queue, no limits. You can even use it offline.
