Gigabit per Second to Megabyte per Second Converter
Convert gigabits per second to megabytes per second instantly. Free, bidirectional, and fully in-browser.
1 gigabit per second equals 125 megabytes per second — enter any gigabit per second value to convert it to megabytes per second instantly. This Gigabit per Second to Megabyte per Second converter is a client-side tool: it applies a single multiplication (MB/s = Gbit/s × 125) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megabytes per second back to gigabits per second. A reference table lists common gigabit per second values already converted, and nothing you enter is sent to a server.

Why use Gigabit per Second to Megabyte per Second Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to megabyte per second → gigabit per second without reloading.
Exact Data Transfer Rate math
The conversion uses the precise factor (MB/s = Gbit/s × 125), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a gigabit per second measurement to megabytes per second for a spec, listing, or report.
- Checking gigabit per second↔megabyte per second figures while comparing products, datasets, or documentation.
- Learning the gigabit per second-to-megabyte per second relationship from the worked formula and the common-value table.
Frequently asked questions
How many megabytes per second are in a gigabit per second?
One gigabit per second is 125 megabytes per second. Multiply the gigabit per second value by 125 to convert. For example, 10 Gbit/s = 1250 MB/s.
What is the formula to convert gigabits per second to megabytes per second?
MB/s = Gbit/s × 125. This tool applies it automatically and shows a worked example: 10 Gbit/s = 1250 MB/s.
Can it convert megabytes per second back to gigabits per second?
Yes. Press the swap button, or type into the megabyte per second field, and the tool converts megabytes per second to gigabits per second using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard data transfer rate definition (MB/s = Gbit/s × 125), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
