Why HP-UX doesn't have df -h?

I was doing patching for a client and was at my first encounter with the HP-UX system. The patching failed due to the space shortage at the mount point. I tried to check the space through df -h and voila there was no such command.......

df -h is so natural with the Solaris and Linux, but why there is isn't so in the HP-UX and one has to calculate the KBs to get the GBs and TBs?

Please enlighten me if the latest versions of the HP-UX have that functionality.
