About this tool
Convert gigabits to megabytes instantly. Free, bidirectional, and fully in-browser.
1 gigabit equals 125 megabytes — enter any gigabit value to convert it to megabytes instantly. This Gigabit to Megabyte converter is a client-side tool: it applies a single multiplication (MB = Gbit × 125) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megabytes back to gigabits. A reference table lists common gigabit values already converted, and nothing you enter is sent to a server.
Open Gigabit to Megabyte Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Gigabit field.
Read the equivalent in megabytes in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert megabytes to gigabits.
The result updates as you type, and the swap button flips the conversion to megabyte → gigabit without reloading.
The conversion uses the precise factor (MB = Gbit × 125), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One gigabit is 125 megabytes. Multiply the gigabit value by 125 to convert. For example, 10 Gbit = 1250 MB.
MB = Gbit × 125. This tool applies it automatically and shows a worked example: 10 Gbit = 1250 MB.
Yes. Press the swap button, or type into the megabyte field, and the tool converts megabytes to gigabits using the inverse of the same relationship.
It uses the standard digital storage size definition (MB = Gbit × 125), not a rounded approximation, so results are exact to the number of decimal places you select.
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.
