Specifying a field width and adding in your desired unit qualifier

   sinfo -o "%n %.3mGB %.3eGB %C"

would give something like

HOSTNAME MEMGB FREGB CPUS(A/I/O/T)
node01   190GB 125GB 60/4/0/64
node02   190GB 171GB 40/24/0/64
node05   93GB   91GB   0/40/0/40
node06   513GB 509GB 0/96/0/96
node07   513GB 512GB 0/96/0/96
node08   513GB 512GB 0/96/0/96
node09   513GB 512GB 0/96/0/96

which isn't exact, but at least maintains some of the differences
between the RealMemory figure, which is statically defined in your
Slurm config anyway, and the reported FreeMemory figure.

Other than that, piping the output into a script/program that
does whatever scaling you want will give you eaxctly what you
want, as you'll have full control over things.
