1 MB is eqilvalent to how much kb?

It should be 1000 but Windows says it to be something else, i calculated it to be 1024, if this is so why is 'kilo'(10^4) used?

1MB is really equal to 1024kb.

To put it simply, computer data is organised in such a way that data capacity is expressed in powers of 2 (for example 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, etc).

"Kilo" is used for convenience in naming, because 1000 is the closest number to 1024 that already has name to it.

1 Mega Byte (MB) = 1024 Kilo Bytes

The prefixes like kilo-, mega-, etc. are used so that there will be no need to formulate new names and create confusion. After all, 1024 is almost equal to 1000.

Moreover, we follow decimal number system (10 digits) and so have multiples of 10, while the computer follows binary number system (2 digits) and similarly follows multiples of 2 (1024 = 2^10).

1 MB is 1024 KB not 1000. I guess they use "kilo" because it's easier to say that than 1024 KB every time, especially when you have a couple MB.

1 kb = 1024 byte

1 mb = 1024 kb

in binary notation: 1024 is considered as 1k

so 1kbytes = 1024 bytes

1Mbytes = 1024 kbytes

ie; 1024 x 1024 bytes.

You are right 1 Mb = 1024 kb.

But whenever you purchase a new hard disk of any size. e.g.-80 GB

Company writes 80 GB size of that hard disk on label. But its not exactly of that size. Hard disk is calculated by company's by 1000 KB=1MB. B'cause when hard disk is divided in sectors its creates some boundaries. So its always counted by 1000KB=1MB in hard disk drive.

Bye....
