If I assume this is an XY problem, and your true goal is find out what
memory pressure a system is under then my answer would be to track the
percent of swap used.  Free memory is a useful utility on Windows XP, not
so much on FreeBSD.

So to answer your question in another way, there is a reason "free" doesn't
exist on FreeBSD.  It's not very meaningful.
