How many kilobytes are in a gigabyte?

Answer 1

There are actually two answers to this, depending on what method you want to use to determine the answer.

Standard definition The standard definition for kilobyte is 1,000 (10^3) bytes, just like there are 1,000 meters in a kilometre.

Likewise, the standard definition for gigabyte is 1,000,000,000 (10^9) bytes. Dividing, this means there are 1,000,000 (1 million) kilobytes (kB) in a gigabyte (GB).

This is the definition used for hard drives, portable memory drives (memory cards, USB drives), DVDs, Blu-ray disks, and most measures of performance. Some software (such as Mac OS X and the Linux kernel) uses this definition when displaying file and disk sizes. Memory manufacturer usage Memory manufacturers use a non-standard system that conflicts with the way everyone else measures. By their definition, a kilobyte (written "KB") is 1,024 (2^10) bytes, and a gigabyte (written "GB") is 1,073,741,824 (2^30) bytes.

The correct name for 1,024 bytes is "kilobinary byte" or "kibibyte". The correct name for 1,073,741,824 bytes is "gigabinary byte" or "gibibyte".

This is approximately equal to the above, but you may need to know it to figure out exact numbers:

By this definition, 1 "GB" = 1,048,576 "KB" More correctly, 1 GiB = 1,048,576 KiB

This definition is used by memory manufacturers and some software, like Microsoft Windows.

Answer 2

There is no such thing as a kigabyte. There are however 1,048,576 kilobytes in a gigabyte.

Answer 3

1gb = 1048576 kb

Answer 4

5242880 kilobytes equals 5 gigabytes

Answer 5

1048576 KB
