About this tool
Convert gigabytes to terabytes instantly. Free, bidirectional, and fully in-browser.
1 gigabyte equals 0.001 terabytes — enter any gigabyte value to convert it to terabytes instantly. This Gigabyte to Terabyte converter is a client-side tool: it applies a single multiplication (TB = GB × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert terabytes back to gigabytes. A reference table lists common gigabyte values already converted, and nothing you enter is sent to a server.
Open Gigabyte to Terabyte Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Gigabyte field.
Read the equivalent in terabytes in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert terabytes to gigabytes.
The result updates as you type, and the swap button flips the conversion to terabyte → gigabyte without reloading.
The conversion uses the precise factor (TB = GB × 0.001), 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 0.001 terabytes. Multiply the gigabyte value by 0.001 to convert. For example, 10 GB = 0.01 TB.
TB = GB × 0.001. This tool applies it automatically and shows a worked example: 10 GB = 0.01 TB.
Yes. Press the swap button, or type into the terabyte field, and the tool converts terabytes to gigabytes using the inverse of the same relationship.
It uses the standard digital storage size definition (TB = GB × 0.001), 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.
