The reason behind this is that Size of the disk in megabytes is obtained by dividing the size of the disk in Bytes twice by 1024. Thus it comes approximately 1985 Meg.
In this way the general formula to calculate the capacity of disk in Millions of byte will be as follows:
Disk Capacity in millions of Byte =
(Cylinders X Heads X Sectors X Bytes per Sector)
__________________________________________M
1,000,000

And general formula for calculating the capacity of the disk in Megabyte will be given as follows:
Disk Capacity in Megabytes =
(Cylinders X Heads X Sectors X Bytes per Sector)
_________________________________________ Meg
1024 X 1024
