Converting bytes and gigabytes
In the conversion tables below, figures are rounded to a maximum of 5 decimal places (7 with smaller numbers) to give approximations.
How many gigabytes are there in 1 byte?
There are 1.0E-9 gigabytes in 1 byte. To convert from bytes to gigabytes, divide your figure by 1000000000 .
How many bytes are there in 1 gigabyte?
There are 1000000000 bytes in 1 gigabyte. To convert from gigabytes to bytes, multiply your figure by 1000000000 .
What is a byte?
It is common for confusion to arise between bytes and bits. A byte represents eight unique bits of information. Each bit will be assigned a value of a 0 or a 1. This entire group of bits will then act as a packet of data. Examples here can be a letter, a number or a symbol such as a question mark. Bytes can be thought of as the "DNA" that is used to form larger strings of data and eventually, entire programs. It is important to keep in mind that unlike the diminutive bit, the byte is used to explain larger numbers.
What is a gigabyte?
A gigabyte is the equivalent of 1,000,000,000 bytes. Still, many fields of computer science will refer to this number as 1,073,741,824 (1,024^3) bytes. This second figure will often be used when speaking about different sizes of RAM within an operating system. To make sense out of this large figure, let's use it in reference:
- 1 gigabyte is 1,000 megabytes.
- 1 gigabyte is 1,000,000 kilobytes.
