That's an empty string, so if you have no data in A or B your result will be
blank instead of zero or the boolean FALSE.

One question re the answer: I understand what is being "said" except the
double quotation marks.

I'm just learning to use Excel.

I want to enter data in either column A (litres) OR column B (US
gallons).
Column C will convert to imperial gallons.

I would like to create a formula in column C that would result in this
logic:

IF there is data in cell "A(n)" then do calculation A(n)/4.54, if no
data
in A(n) and there is data in cell "B(n)" then do calculation B(n)*.83
