 In the example above, there is a call of **preferredUnits** function. You can provide identifiers to get preferred units for them and eventually receive properly calculated values from queries. The units will be chosen automatically based on you current localization. This is only required for **QuantityTypes**. If you will try to provide invalid unit for a type, you will get an error.
