Human readable disk space

Hello List,

Im using xymon for many years
I just wondering is there a easy way to make the output more readable?

Filesystem             1024-blocks      Used  Available Capacity Mounted on
/dev/mapper/sysvg-root    10321208   4397592    5399328      45% /
/dev/sda1                  1032088    152244     827416      16% /boot
/dev/mapper/sysvg-vz    1898719656 249544968 1552725360      14% /vz

As you see there is no scaling in the output to GB etc

Thanxs

Steffan
