About converting Terabytes to Bits
Terabytes (TB) and Bits (bit) are both units of digital storage, so converting between them is a single multiplication: multiply your Terabytes figure by 8,000,000,000,000. Ten Terabytes comes to 80,000,000,000,000 Bits, and a hundred works out at 800,000,000,000,000 Bits.
Rule of thumb: going from Terabytes to Bits multiplies, so the figure always grows — one Terabyte is already 8,000,000,000,000 Bits. If your answer came out smaller, you have the conversion the wrong way round.
What is a Terabyte?
A terabyte is a trillion bytes, and it is the unit that makes the decimal-versus-binary confusion impossible to ignore: buy a 1 TB drive, plug it into Windows, and it reports roughly 931 GB. Nothing is missing and nobody has short-changed you — the manufacturer counted in decimal terabytes, as SI defines them and as this site does, while Windows divided by 1,024 three times and still wrote "GB" on the result. The honest label for what Windows shows is 931 GiB. macOS and Linux mostly report decimal now; Windows still does not.
What is a Bit?
A bit is a single binary digit — one yes or no, the smallest thing a computer can distinguish. The name is a contraction of "binary digit", credited to John Tukey and made famous by Claude Shannon’s 1948 paper founding information theory. The practical thing to know is that bits and bytes live in different places: connection and network speeds are quoted in bits per second, while file sizes are in bytes. That is why a 100 Mbps line downloads at about 12.5 MB/s and people assume they have been cheated. Nobody has — the two figures are counting different things.
To put both in perspective: a 1 TB drive shows up as about 931 GB in Windows, while a bit is a single yes-or-no.

Frequently asked questions
How many Bits are in one Terabyte?
There are 8,000,000,000,000 Bits in one Terabyte.
How do I convert Terabytes to Bits?
Multiply the number of Terabytes by 8,000,000,000,000. For example, 10 Terabytes = 80,000,000,000,000 Bits.
What is 100 Terabytes in Bits?
100 Terabytes is equal to 800,000,000,000,000 Bits.
How do I convert Bits to Terabytes?
Multiply the Bits value by 0 (or divide by 8,000,000,000,000).
Is this Terabytes to Bits conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Terabyte = 8,000,000,000,000 Bits is the complete value — nothing is rounded away.
