Units Find an example of how to create a question with units below. See which units and metric prefixes are available. Example Let us create a basic question with units: We need to select Quantity and make sure that meters and prefixes are selected The algorithm is very simple: Note that since Quantity is selected, the units are highlighted in blue. s and l are also highlighted because there exist the units second and liter, but since they are preceded by #, they are interpreted as variable name.
