About converting Bytes to Gigabytes
Bytes (B) and Gigabytes (GB) are both units of digital storage, so converting between them is a single multiplication: multiply your Bytes figure by 0.000000001. Ten Bytes comes to 0.00000001 Gigabytes, and a hundred works out at 0.0000001 Gigabytes.
Rule of thumb: going from Bytes to Gigabytes divides, so the figure always shrinks — it takes about 1,000,000,000 Bytes to make a single Gigabyte. If your answer came out bigger, you have the conversion the wrong way round.
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.
What is a Gigabyte?
A gigabyte is a billion bytes in SI terms, and it is the unit consumers actually shop in: phone storage, mobile data allowances, game downloads. It is also where the decimal-versus-binary split gets genuinely interesting, because the answer depends on the product. Drives and data plans are sold in decimal gigabytes; memory is not, and an "8 GB" RAM module really is 8 GiB, because memory is physically addressed in powers of two and could not be built in round decimal sizes. Windows then reports both using binary units labelled "GB".
To put both in perspective: a byte holds a single letter of plain text, while an hour of HD streaming video runs to a few gigabytes.
