It comes from the check_disk plugin, not nagios. Interestingly, the  
default units _are_ megabytes so I think you might have specifically  
set it to show KB instead. Take a look at your check_disk command  
definition to verify you didn't specify -k and/or make sure you're  
using -u or -m properly.

[libexec]$ ./check_disk --help

This plugin checks the amount of used disk space on a mounted file  
system
and generates an alert if free space is less than one of the threshold  
values


Usage: check_disk -w limit -c limit [-W limit] [-K limit] {-p path | - 
x device}
[-C] [-E] [-e] [-g group ] [-k] [-l] [-M] [-m] [-R path ] [-r path ]
[-t timeout] [-u unit] [-v] [-X type]

Options:
  -h, --help
     Print detailed help screen

[chop chop snip snip ohwhatareliefitis]

  -k, --kilobytes
     Same as '--units kB'
  -m, --megabytes
     Same as '--units MB'
  -u, --units=STRING
     Choose bytes, kB, MB, GB, TB (default: MB)
