We can't seem to convert some units properly. This is what we have:

(in a for loop to print out the original units)
Units: 
oldUnits: Cel
oldUnits: Cel
oldUnits: degrees_north

We then change all the Cel (celsius) units to Kelvin by doing this:

Unit[] newUnits = Unit.copyUnitsArray(oldUnits);
Unit toUnit = SI.kelvin;

for (int i=0; i < oldUnits.length; i++) {
    if (newUnits[i].toString().equals("Cel")) {
        newUnits[i]=toUnit;
    }
}

Printing out the new units array:
(in a for loop to print out the new units)
Units: 
newUnits: K
newUnits: K
newUnits: degrees_north

We then create a FlatField ie.

FlatField newField
    new FlatField((FunctionType) field.getType(),
                  field.getDomainSet(),
                  null, 
                  null,
                  field.getRangeSets(),
                  newUnits);

When I printed out the contents of newField, this is the output I get:
Component: 0    Type: MinTemp   Value: NaN      Units: Cel
Component: 1    Type: MaxTemp   Value: NaN      Units: Cel
Component: 2    Type: WindDir   Value: NaN      Units: degrees_north

which is wrong. We want to convert the units for Component 0 & 1 to
Kelvin but it keeps returning "Cel". Can anyone identify what we're doing
wrong please?
