In computer science the set of units of measure of information is used. However such unit as "byte" and derivative of it – kilobyte (kb), Megabyte (MB), Gigabytes (GB) and Terabyte (Tb) is generally put into practice. For calculation of the necessary place on a disk of the computer or time of loading of the file these units often should be transferred each other. For example, kb in MB. Many at the same time just divide quantity kilobyte into 1000 and receive not absolutely correct result.

Instruction
1. To transfer kb to MB (kilobytes in megabytes), divide quantity kilobyte into number 1024. That is: Kmb = Kkb / 1024, where Kmb – the number of megabytes (MB), Kkb – quantity kilobyte (kb). For example, the volume of a standard 3rd inch diskette is 1440 kb. To estimate how many megabytes of information will go in on this carrier, divide 1440 for 1024. Number 1.40625 will turn out. So many megabyte of information can be written down on a diskette, but not 1.44 MB as it turns out at approximate calculation.
2. If near at hand there is no calculator, then it is possible to transfer kilobytes to megabytes approximately. For this purpose just separate a decimal point three last signs in number of kb. That is use a formula: Kmb ≈ Kkb / 1000, where Kmb – the number of megabytes (MB), Kkb – quantity kilobyte (kb). However at the same time it is necessary to consider that the result turns out a little more true value. When calculating file size this mistake is not critical. On the contrary, as the file will look slightly more, it for certain will go in on the place allocated for it. But at free space assessment (on a disk, a flash card, the memory card) such inaccuracy can cause unexpected problems.
3. After close translation of kb in MB consider also that three figures standing right after a decimal point designate not quantity kilobyte, and thousand shares of megabyte. That is if in an example with a diskette its volume (in round figures) is 1.406 MB, then it one means "the whole four hundred six thousand megabytes", but not 1 MB and 406 kb. Visually to estimate the size of this very often found mistake, just subtract from diskette volume (in kb) the volume of one megabyte (also in kb). 416 kb will turn out 1440 – 1024 =. Thus: 1.406 MB = 1 MB and 416 kb that on 10 kb exceeds wrong result.
