Here are details on the common file systems: Here is a list of some of the commonly used units in the metric and their corresponding IEC binary prefixes: Nameįile sizes are limited by the file system that is used and its implementation. So bear in ming that when purchasing a new hard drive or memory card. Of course the new naming convention is very welcome for the storage manufacturers as they now provide 10% less storage while using the same naming convention. Windows still uses the old unit naming convention which causes the discrepancy. If you are purchasing a storage device you can see that a 2TB hard drives displays as 1.82 TB which is much smaller in Windows. There was no perfect solution so we have to get used to it. It would be much less confusing to use new unit names, but that would not correspond to the metric system naming convention. Changing something existing and well established and known by billions of people in my opinion is not a good idea, but it is my own personal position. The old multiples of 1024 units are now with new prefixes and mebibyte is 1024 kibibytes and a kibibyte is 1024 bytes. Megabyte is now 1000 kilobytes which on the other hand is one thousand bytes. If you were using computers for a long time you may think that a megabyte is still 1024 kilobytes, but that is no longer the case. In 1998 IEC introduced new naming convention for the file sizes which now creates even more confusion. 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. That is because computers use the binary system - not the decimal. Where does the 1024 number come from? Well most numbers in computers are 2 to the power of X, and 1024 is 2 to the power of 10. Why 1 Megabyte is 1024 Kilobytes Instead of 1000 Kilobytes? This is a bit different than in metric system where values are divided by 1000 to convert them to the next larger unit. To convert from kilobytes to megabytes you have to divide the kilobytes to 1024 again and so on. To further convert the bytes to kilobytes you have to divide the value by 1024. To convert bits to bytes you have to divide the count of bits to eight as one byte contains 8 bits. Converting file sizes is similar to converting other units with some small differences. #ARE FILES IN JOTTACLOUD SAVED FULL SIZE WINDOWS#You can find the list of IEC metric and binary names in the table at the end of this article.Ĭompatible with Windows 11/10/8.1/8/7/Vista (Both 32 & 64 Bit)Īs already described the smallest unit in computers is the bit. In order to correct this mess the International Electrotechnical Commission (IEC) approved a new IEC International Standard in December 1998. Though the kilo prefix in the metric system means 1000 (e.g. The next larger units after the byte are named kilobyte, megabyte, gigabyte, terabyte and so on which lead to great deal of confusion. The next unit larger than the bit is the byte which is formed by the combination of eight bits and can represent a value from 0 to 255 which is 2 to the power of 8 - all the possible combinations of the 8 bits that it includes. The bits are combined in groups in order to form larger units. The zero is also known as false (off) state and the one is known as true (on). A bit has only two digits - zero and one. The smallest unit in computers is bit and comes from binary dig it. File size measures the size of a computer file and is typically measured in bytes with a prefix.
