Actually, I believe it reports based upon the contents of the BLOCKSIZE
environment variable which is 1k or 1024 bytes for the purposes of this
discussion. In either case, you'll notice that the reporting shown below
accurately shows that the users quota is very near the limit and the quota
is set at 350MB. 

Interestingly enough, I added check_quotas="YES" to /etc/rc.conf and
rebooted. That fixed that users quota problem. I'm not sure if it was the
rebooting (and clearing the kernels idea of what the quota should be) or if
running quotacheck in single user mode did it. I have to guess the former
because quotacheck's results should not vary dependent on whether the
machine is single user or not.
