I think I've asked this question before and I had the formula, but I can't
seem to find it.

How do I convert the number of block on a partition to either kbytes or
Megabytes?

Thanks

Hello,

Try df -h this will print free space in human readable form, e.g. Mb,
Kb, etc....

The problem is that these are raw devices, I cannot use df on them. I used
fdisk to partition the devices and now I have the output of fdisk with the
number of blocks per partition and I want to know exactly how many kbytes or
megabytes each partition is.

Here's the output of fdisk:

Disk /dev/emcpowera: 16.1 GB, 16106127360 bytes
255 heads, 63 sectors/track, 1958 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/emcpowera1 1 491 3943926 60 Unknown
/dev/emcpowera2 492 982 3943957+ 60 Unknown

Hello,

1 Block == 1Kbyte

which means each of your devices is around 4Go...

Actually disk blocks used to be 512 bytes at the low level - in fact
this calculation was used in some of the early procs used for converting
pages to blocks - and the 512 in the calculation seems suggest this is
still true. The 1K maybe the inode division level.
