Though the kilo prefix in the metric system means e. You can find the list of IEC metric and binary names in the table at the end of this article. As already described the smallest unit in computers is the bit. Converting file sizes is similar to converting other units with some small differences. To convert bits to bytes you have to divide the count of bits to eight as one byte contains 8 bits.

To further convert the bytes to kilobytes you have to divide the value by To convert from kilobytes to megabytes you have to divide the kilobytes to again and so on. This is a bit different than in metric system where values are divided by to convert them to the next larger unit. For example 1 km is meters. Where does the number come from? Well most numbers in computers are 2 to the power of X, and is 2 to the power of That is because computers use the binary system - not the decimal.

Of course you can represent the decimal or any other system on a computer, but at its core hardware level the computer uses the binary system. In IEC introduced new naming convention for the file sizes which now creates even more confusion. If you were using computers for a long time you may think that a megabyte is still kilobytes, but that is no longer the case. Megabyte is now kilobytes which on the other hand is one thousand bytes.

The old multiples of units are now with new prefixes and mebibyte is kibibytes and a kibibyte is bytes. A byte is a sequence of 8 bits. For example, one alphanumeric character uses one byte of memory. A kilobyte represents bytes in the binary system and bytes in the decimal system. A megabyte is kilobytes and so on. Although computer data is practically measured in binary system so 1 KB is made of bytes, for simplicity the decimal system was added so 1kB is made of approximately bytes.

These can be found easily in any operating system. This compensation may impact how and where products appear on this site including, for example, the order in which they appear. TechnologyAdvice does not include all companies or all types of products available in the marketplace.
