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