The concatenation operator is: ||


hectares||' ha'

You can also append text or put spaces between using alternate quotations:

 "Streetnum" || ' ' || "Streetname"

You can use tostring() to concat number fields Ex hectares || ' ha' || tostring(id)

Yes! Using the field calculator, the syntax is: FIELDNAME || FIELDNAME

EDIT: This works on string fields or string-integer combinations. With Integers, it will just perform the math and add the fields together.
