About this tool
Convert gigabytes to megabytes instantly. Free, bidirectional, and fully in-browser.
1 gigabyte equals 1000 megabytes — enter any gigabyte value to convert it to megabytes instantly. This Gigabyte to Megabyte converter is a client-side tool: it applies a single multiplication (MB = GB × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megabytes back to gigabytes. A reference table lists common gigabyte values already converted, and nothing you enter is sent to a server.
Open Gigabyte to Megabyte Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Gigabyte 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 gigabytes.
The result updates as you type, and the swap button flips the conversion to megabyte → gigabyte without reloading.
The conversion uses the precise factor (MB = GB × 1000), 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 gigabyte is 1000 megabytes. Multiply the gigabyte value by 1000 to convert. For example, 10 GB = 10000 MB.
MB = GB × 1000. This tool applies it automatically and shows a worked example: 10 GB = 10000 MB.
Yes. Press the swap button, or type into the megabyte field, and the tool converts megabytes to gigabytes using the inverse of the same relationship.
It uses the standard digital storage size definition (MB = GB × 1000), 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.
