Example 1: Units

Let us create a basic question with units:

We need to enable the units and prefixes we want to use in Input options > Input syntax. You can check only those units and prefixes you are interested in or use the All tab.

Then, we need to generate the random variable, which will be requested to be converted, and the corresponding correct. We'll add a as a basic random variable accordingly, and the correct answer inside the evaluate command.

Finally, you can also select the Match unit of measure validation option to force the student's answer to be expressed in meters.
