What we have

which are singular and then in the schema "unit"

    ❯ git grep -h unit: | sed -e 's,^[- ]*,,g' | sort | uniq -c | sort -n
          1 unit:
          1 unit: cm
          1 unit: degrees
          1 unit: g/mL

          1 unit: mL/s
          1 unit: 'mm^2'
          1 unit: mT.s/m

          1 unit: rad
          1 unit: um
          1 unit: uT
          1 unit: year
          2 unit: cm/s
          2 unit: ms
          2 unit: mT/m
          3 unit: 1/s
          3 unit: degree
          4 unit: m
          6 unit: mm
         12 unit: Hz
         20 unit: arbitrary
         49 unit: s

also singular.
