terabyte to gigabyte Converter
Convert TB to GB and back with a live reference table.
1 TB = 1000 GB\n5 TB = 5000 GB\n10 TB = 10000 GB\n25 TB = 25000 GB\n50 TB = 50000 GB\n100 TB = 100000 GB
Why this conversion matters
Decimal terabytes and gigabytes are used by most drive makers and cloud storage plans. The widget keeps the direction explicit so you can enter either side of the pair without doing the reciprocal by hand. It is built for quick checks where a calculator, specification sheet, recipe, map, or lab note uses the other unit.
For the default example, 1.5 TB converts to 1500 GB. Switching the direction shows the inverse relationship, so 1500 GB converts back to 1.5 TB with the same factor.
Formula and privacy note
The calculation uses 1 TB = 1000 GB. Forward conversion multiplies by that factor, and reverse conversion divides by it. Results are rounded to six significant figures for readable estimates, so very small scientific units and large planning units stay scannable. Check the unit labels before copying a result, especially when similar abbreviations appear in the same project. The reference table is generated from the same constant, and everything runs locally in your browser.
Frequently Asked Questions
What factor does this converter use?
It uses the standard factor 1 TB = 1000 GB, then applies the reciprocal for the reverse direction.
Why are results rounded?
The main result is rounded to six significant figures so very large and very small values stay readable while preserving the useful precision for quick checks.
Can I convert both directions?
Yes. Choose TB to GB or GB to TB from the direction menu and the output updates immediately.
Is this converter private?
Yes. The conversion runs entirely in your browser, and the value you enter is not uploaded or stored.
