Welcome to **GB to kB**, you have found the right page. In order to change these units of data or information, multiples of the fundamental unit byte (B), it is necessary to understand that the term “gigabyte” (GB) has more than one interpretation. If you like to get gigabytes in kilobytes (kB), then it makes a difference whether a GB stands for 1,000 or 1,024 bytes. Read on to learn all about gigabytes to kilobytes, and check out our converter further below.

## Gigabytes to Kilobytes

The IEC (International Electrotechnical Commission) defines one GB as 1,000,000,000 (10^{9}) bytes. This standard has been established in 1998 and widely been accepted such as by the International System of Units (SI), the metric system in modern form, so to speak. At the same time, the kilobyte has been defined as 1,000 (10^{3}) bytes. Throughout our website we stick with the SI/IEC standard. Yet, some companies have a different opinion, as detailed below.

The decimal prefix “giga” stands for one billion (10^{9}), whereas the decimal prefix “kilo” denotes one thousand (10^{3}). It follows that gigabytes to kilobytes is always one million times more, as one gigabyte equals 1,000,000 kilobytes. In other words, 1,000,000 kB = 1 GB.

Alas, the term gigabyte is sometimes used with a different interpretation:

For instance, Microsoft (Windows operating systems) claims that a GB is equivalent to 1024 bytes. They state that bytes are computed in powers of 2, and therefore should be expressed in powers of 2, too. With this in mind, 1 gigabyte = 1024^{3} B and 1 kilobyte = 1024^{1} B, etc.

## Gibibytes to Kibibytes

However, according to the standards bodies, 1,024 bytes matches one kibibyte (KiB), and, in the same vein, 1,073,741,824 bytes (1024^{3} B) make up a gibibyte (GiB). In between the kibibyte and the gibibyte is the mebibyte (MiB): 1024^{2} B.

Manufacturers of hard storage devices regularly measure their drives, e.g. SSD, in multiples of 1,000,000,000 or 1,000,000,000,000 bytes, in other words in gigabytes or in terabytes.

Volatile storage, e.g. Random Access Memory, is often remains labeled in “kB”, too. However, in this case a kB often means 2^{30}= 1024^{3} = 1,073,741,824 bytes, that is a kibibyte.

Make sure to remember Microsoft’s point of view which is that one kB is equal to 1,073,741,824 B. In our article kB to GB, you can find an example of how the differences between gibibytes and gigabytes adds up.

## GB in kB

In base 10 definition a GB equals 10^{9} B and a kB = 10^{3} B. In base 1000, a GB is 1000^{3} B, and one kB is 1000^{1} B. One kilobyte = 1/1,000,000 gigabytes.

### GiB in KiB

In base 2 definition, one GiB = 2^{30} B and a KiB equals 2^{20} B. In base 1024, a GiB is 1024^{3} B and a KiB is 1024^{1} B One gibibyte = 1/1,048,576 kibibytes.

## How many kB in a GB?

Have you been searching for *how many kB in a GB*? Provided that you have read our information, then you are mindful of the fact that you have to differentiate if your capacity device is non-volatile or volatile, and to take into consideration vendor opinions, too. As already stated clearly, we stick with the official standards. Please keep that in mind when making use of our app in the next section.

## Convert GB to kB

In order to change gigabyte to kilobyte you can either use our formula [kB] = [GB] x 1000000, or fill in the GB kB calculator below, which is what we recommend.

### Converter

So as to conduct a conversion from GB to kB enter a value in gigabytes. Our tool then does the math on the fly, without a convert button. This *GB to kB* calculator processes inputs in gigabytes, gibibytes, kilobytes and kibibytes, and automatically converts it into all other multiples of the base unit byte.

Frequently searched conversions on this site include, for example:

## GiB to KiB

By now, you are certainly aware that gibibytes to kibibytes is not the same as gigabytes to kilobytes. It is recommended using our converter to change GiB to KiB.

Below you can locate our overview of the common units of digital storage or memory:

Metric Multiples of Bytes:

- 1
**kB**(kilobyte) = 10^{3}bytes = 1000^{1}B - 1
**MB**(megabyte) = 10^{6}bytes = 1000^{2}B - 1
**GB**(gigabyte) = 10^{9}bytes = 1000^{3}B - 1
**TB**(terabyte) = 10^{12}bytes = 1000^{4}B - 1
**PB**(petabyte) = 10^{15}bytes = 1000^{5}B

Binary Multiples of Bytes:

- 1
**KiB**(kibibyte) = 2^{10}bytes = 1024^{1}B - 1
**MiB**(mebibyte = 2^{20}bytes ) = 1024^{2}B - 1
**GiB**(gibibyte) = 2^{30}bytes = 1024^{3}B - 1
**TiB**(tebibyte) = 2^{40}bytes = 1024^{4}B - 1
**PiB**(pebibyte) = 2^{50}bytes = 1024^{5}B
