Enter units for numerical responses
When you are asked to enter units for numerical questions, any of the units in the tables below are allowed, along with Standard SI prefixes for metric units.
Learning Catalytics also accepts equivalent responses that use different numbers and units, and compound units. For information about including these units in expressions, see Enter algebraic expressions.
Important: If you are asked to include units, your answer will be considered incorrect if you do not add units. All units—including currency units—need to be appended to your answer to be graded correct.
Examples
