For B1:
=MAX(3,A1)
and copy down column B as far as required.

Or, if you want nothing to show in B1 until there is something in A1:
=IF(A1="","",MAX(3,A1))

I need the formulae for

if cell A1 = 2.4 B1 = 3
A2 = 7.6 B2 = 7.6
want formulae for B1,B2 etc, in other word if the value is less than <3,
to
= 3, all other values 3 to record as that value

Can you please help?
