When formatting a unit which is Units.UNITY scaled to some value, since Units.UNITY has no symbol, attempts to format it produce confusing strings. Example with the number of icebergs per 100 km²:
|Symbol in netCDF file:||1e-2 km-2|
|SIS 0.8 representation:||1.0E-8⋅∕m²|
Note the multiplication immediately followed by division sign above.
