Answer 1

Make sure you are using the right formula and have the number format as general.

Answer 2

If you have the unique IDs in column C, and want the average on column D, and row 1 has the titles, you could use this formula in cell D2:

=averageifs(b$1:b$1000, a$1:a$1000, d2)

It means "Average the number in column B if what is in column A matches D2".

Fill down the formula.

Then select column D, press Ctrl-1 (with the numbers on top of the letters) to go to format, and in "General" type [mm].

Answer 3

AVERAGEIF is enough:

=AVERAGEIF(A:A;D2;B:B)

Cell format [mm]
