About converting Terabytes to Bytes
Terabytes (TB) and Bytes (B) are both units of digital storage, so converting between them is a single multiplication: multiply your Terabytes figure by 1,000,000,000,000. Ten Terabytes comes to 10,000,000,000,000 Bytes, and a hundred works out at 100,000,000,000,000 Bytes.
Rule of thumb: going from Terabytes to Bytes multiplies, so the figure always grows — one Terabyte is already 1,000,000,000,000 Bytes. 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 Byte?
The byte is the unit computers actually store things in, and it has not always been eight bits. Werner Buchholz coined the word at IBM in 1956, when a byte meant however many bits a particular machine needed to hold one character — six, seven and nine-bit bytes all existed. Eight bits became the standard with the IBM System/360, and the industry never looked back. Because that old ambiguity was real, networking standards still say "octet" when they want to be unmistakable about meaning exactly eight bits.
To put both in perspective: a 1 TB drive shows up as about 931 GB in Windows, while a byte holds a single letter of plain text.
