# Require Units in Numerical Questions

You can require your students to enter a unit with their response by adding the correct unit after the numeric value in Answer.

If you specify units, any equivalent answer specifying equivalent units is accepted.
For example, your student could respond `1 mi` or
`5280 ft`. You can configure your assignments to award
partial credit for specifying compatible units even if the numerical part of the
response is incorrect.

By default, answer format tips tell your students whether units are checked. You can hide answer format tips for your assignments.
