Users may now choose from a selection of distance units to override the default (Canvas CRS map units) for elevation profiles in both the interactive elevation profiles (via the settings toolbar button) and for layout elevation profiles.
In layout profiles, there is an additional option which controls where the distance unit suffixes should be placed. The following options are available to manage the display of unit suffixes:

• hide the suffixes
• display for all values
• display for the first value
• display for the last value
• display for both the first and last values.

Note that it is currently not possible to expose unit selection for the vertical axis, as this is currently dimensionless and will require the development of vertical CRS handling in QGIS as outlined in QEP 267.
