Matt,
UREL and VREL are in m/s as defined in the grib product from
which they are decoded (parameter #'s 33 & 34) using table
$GEMTBL/grid/wmogrib2.tbl

The above table defines the parameter names, units, scaling for
the corresponding grib parameter id from the model output.

To output in knots, KNTV(UREL) and KNTV(VREL).
