how do i work i pints and gallons

[boss steve]

i would like to have a column that works in pints and gallons that will add
up at the bottom.
so if i put in 1.4 (1 being a gallon & .4 being pints) + 2.7 (2 being a
gallon & .7 being pints) the answer i need would be 4.3
as there are 8 pints in a gallon

Using Excel 2007

Hi,

I may have made hard work of this and someone may come up with something
simpler but in the meantime try this ARRAY formula. There musn't be any blank
cells in the range and see below on how to enter an array formula

=SUM(INT(A1:A10))+MOD(SUM(MOD(A1:A10,INT(A1:A10)))*10,8)/10+INT(SUM(MOD(A1:A10,INT(A1:A10)))*10/8)

This is an array formula which must be entered by pressing CTRL+Shift+Enter
'and not just Enter. If you do it correctly then Excel will put curly brackets
'around the formula {}. You can't type these yourself. If you edit the formula
'you must enter it again with CTRL+Shift+Enter.

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

David,

I knew about the Div/0 for blank cells and mentioned it in my response but
never tested it with (say) 0.n values. Thanks for pointing that out.

I was just looking at your formula to understand how you avoided div/0 for
blank cells and see it now.

Your solutions is much better than mine

Somewhat late, but I spend time thinking about this when I should have been
otherwise occupied in church this morning
=SUM(INT(A1:A10))+INT(SUM(MOD(A1:A10,1))*10/8)+MOD(SUM(MOD(A1:A10,1)),0.8)

Enter as array formula (CTRL+SHIFT+ENTER)
Just a bit shorter than David's
