Q:

how to convert this excel formula in english words?

can someone please translate this excel spreadsheet cell formula in english words ?
=ROUND(IF(F28 < 1568,2.5,IF(F28 < 2491,0.004873 * F28-5.142,0.02269*F28^0.7329)),2)

am creating a program based from that formula, but i don't understand which one will go first. atleast i understand this part IF(F28 is less than 1568) ...then what?

A:

Start from the outer if statement and move inwards.  The comma in the IF function separates the statements like :
boolean expression, true part, and false part
The following is the psuedo code of the above.  All the Round are to two decimal places.
IF (F28 < 1568) THEN
  ROUND (2.5)
ELSE IF (F28 < 2491) THEN
  ROUND (0.004873 * F28 - 5.142)
ELSE
  ROUND (0.02269 * F28^0.7329)
