A very common task in the IT industry is needing to convert between storage size units – bytes, kilobytes, megabytes, gigabytes, terabytes, etc. To make things even more complicated, the POSIX standard also specifies that the default output for commands like “df” and “du” must be in 512 byte block sizes.This post will cover a very simple and easy way to quickly convert between any of these units. A kilobyte/megabyte/gigabyte versus a kibibyte/mebibyte/gibibyteHistorically there has been a discrepancy/dispute on how much space a kilobyte, megabyte, and gigabyte represented. If you ask a hard drive manufacturer, they would say a gigabyte is 1,000,000,000 bytes.
However, most Operating Systems calculated a gigabyte as 1,073,741,824 (which is 1024.1024.1024). This is about a 7% discrepancy, and as sizes increase the discrepancy gets larger (for example a terabyte has about a 9% discrepancy).Editor’s Note:Guest author Brian Smith is an AIX/Linux systems administrator in Colorado. You can follow Brian on Twitter at and see his blog atThe solution to all this was that the official definition of a “Gigabyte” is now 1,000,000,000 bytes, and a “Gibibyte” is 1,073,741,824.

FAQ Understanding file sizes (Bytes, KB, MB, GB, TB) A byte is a sequence of 8 bits (enough to represent one alphanumeric character) processed as a single unit of information. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits). History/origin: The gigabyte is based on the byte, which is derived from the bit, and is a unit that makes use of SI (International System of Units) prefixes. The gigabyte is most commonly understood in terms of its decimal definition of 1000 3 bytes. There is also however, a binary definition where a gigabyte is 1024 3 bytes.
See this for much more information.I don’t know about you, but I have never actually heard another person say the word “Gibibyte”. Throughout the rest of this post I will refer to a gigabyte as 1,073,741,824 bytes as this is the common use among people even if it is incorrect per the textbook definition.

The wrong way to convert between size unitsMany people will look at a file size such as 54,183,672,092 bytes and say it is “54 Gigabytes” based on the first 2 digits of the number. In fact, it is really 50.5 Gigabytes (54,183,672,092 divided by 1,073,741,824 (size of 1 GB) equals 50.5 GB).
The larger the file size, the bigger the discrepancy will be between the size it appears to be at first glance and the actual size. The quick and easy method to convert between size unitsThere is an extremely fast and easy way to do any of these conversions. With this method the only number you need to memorize is 1024. The only other thing you need to know is the name/order of the sizes (kilobyte, megabyte, gigabyte, terabyte). To convert smaller units to larger units (i.e.
Take bytes and convert to kilobytes, megabytes, gigabytes, or terabytes) you simply divide the original number by 1,024 for each unit size along the way to the final desired unit.For example, if you wanted to convert 110,214,321,212 bytes to megabytes, you would divide by 1,024 (to first convert to KB), and then divide by 1,024 again (to end up in MB). If you wanted to convert to gigabytes, you would divide by 1,024 three times (once to get to KB, once to get to MB, and then once to end up in GB).To convert larger units to smaller units (i.e. Take a number of gigabytes and convert it down in to megabytes, kilobytes, or bytes) you simply multiply the original number by 1,024 for each unit size along the way to the final desired unit. For example, if you want to convert 384 megabytes to bytes, you would simply multiply it by 1,024 two times (first time to convert to KB, and the second time to end up in bytes).If you wanted to convert 14 terabytes to the number of bytes, you would multiply 14 by 1,024 four times (first to convert to GB, then to MB, then to KB, and then to bytes).
