Sector

The main unit of measurement is a sector. A sector size is 512 bytes. A sector can be addressed either directly by its number or by setting a composite address, consisting of the cylinder (track) number, the head (side) number and the sector number on the track. The correspondence between the two notations is as follows: Sector number = (cylinder number × number of heads× number of sectors) + (head number × number of sectors) + (sector number -1)

One is deducted because the count is kept from zero.
