To be totally correct, use -uS, as when info is displayed in block
units, some rounding of the size might occur.

Compare this:

[root at runchik ~]# sfdisk -l /dev/sda

Disk /dev/sda: 8923 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

   Device Boot Start     End   #cyls    #blocks   Id  System
/dev/sda1   *      0+     12      13-    104391   83  Linux
/dev/sda2         13     143     131    1052257+  82  Linux swap
/dev/sda3        144    8922    8779   70517317+  8e  Linux LVM
/dev/sda4          0       -       0          0    0  Empty

With this:

[root at runchik ~]# sfdisk -uS -l /dev/sda

Disk /dev/sda: 8923 cylinders, 255 heads, 63 sectors/track
Units = sectors of 512 bytes, counting from 0

   Device Boot    Start       End   #sectors  Id  System
/dev/sda1   *        63    208844     208782  83  Linux
/dev/sda2        208845   2313359    2104515  82  Linux swap
/dev/sda3       2313360 143347994  141034635  8e  Linux LVM
/dev/sda4             0         -          0   0  Empty
