You can use the -B option.

-B, --block-size=SIZE use SIZE-byte blocks

All together,

df -BG

If you also want it to be a command you can reference without remembering the arguments, you could simply alias it:

alias df-gb='df -BG'

So if you type:

df-gb

into a terminal, you'll get your intended output of the disk usage in GB.

EDIT: or even use just df -h to get it in a standard, human readable format.

-g is not an valid option – Mottled 6/6, 2013 at 12:37

@Mottled Ah, well, perhaps then using fedorqui suggestion of df -BG and aliasing that for ease of use. – Gaberlunzie 6/6, 2013 at 12:41

@Mottled I've updated my answer to reflect the correction of my derp. – Gaberlunzie 6/6, 2013 at 14:31
