 The statement in squid.conf.documented is accurate: When parsing
size-related options that support units, Squid interprets the KB suffix
as 1024 bytes. This classic/legacy interpretation predates and violates
some of the modern conventions/standards. I do not anticipate changes in
this area because it is not trivial to make such changes
backwards-compatible, and because we should solve much bigger problems
first.

Please note that Squid may use a different KB definition in other
contexts, especially in various reports and cache.log messages.
