terabit to gigabyte
Convert terabit (Tbit) to gigabyte (GB). Use an editable data storage converter, conversion formula, and reference table.
1 Tbit = 125 GB
Conversion formula
One terabit equals 125 gigabyte. Multiply your value in terabit by this factor to get gigabyte. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 terabit:5 × 125 = 625 GB

About these measurements
Data storage expresses a number of bits or bytes.
The base reference used here is the byte. One terabit is 125,000,000,000 base units; one gigabyte is 1,000,000,000 base units.
Important distinctions
Decimal prefixes use powers of 1,000; binary prefixes use powers of 1,024. One byte is eight bits.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert Tbit to GB?
Multiply the quantity in Tbit by 125. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the gigabyte to terabit converter.
