A large quantity of data has been captured with units of measurement included in same cell as values. e.g. 65 kg or 1.2 metres



I have tried =AVERAGE(VALUE(LEFT(A13:A66,)))

But get a #VALUE error.

Please can someone explain how to property use the VALUE and LEFT functions or provide the correct formula.

Something like =(SUMPRODUCT(--LEFT(A1:A2,FIND(" ",A1:A2))))/COUNTA(A1:A2)

( adapt range as needed)

Can't get that SUMPRODUCT formula to work Pecoflyer.

If helper cells are acceptable I would put in B13 the formula:

LOOKUP(9^9,--LEFT(A13,ROW($1:$100))) and copy down to B66 and then use =AVERAGE(B13:B66).

If helper cells are not acceptable the following array formula seems to work:

=AVERAGE(IF(ISNUMBER(--MID($A$13:$A$66,1,FIND(" ",$A$13:$A$66)-1)),--MID($A$13:$A$66,1,FIND(" ",$A$13:$A$66)-1)))


Edit: My apologi to Pecoflyer. SUMPRODUCT formula does work if no empty cells, otherwise it doesn't.
