A UFS file system has a fixed number of inodes, set when the file system is created. df can simply report how many of those have been used, and how many are free.
Most file systems, including ZFS and QFS, allocate inodes dynamically. In this case, there really isn’t a “number of files free” that df can report. The best that we can do is to “guess” how many files you might be able to create, but this will differ depending on file size, and may change depending on other I/O activity, since the available free space is used not only for inodes, but for other data or metadata on the file system. What are you trying to do based on this number? If you are simply trying to determine whether it should be possible to create a given number of files, for instance to preflight a copy operation, you could use the df/stat() result as a hint, though it may not be accurate.
