I am trying to do a simple calculation using a coefficient of thermal expansion. But the result is not as expected. The units of thermal expansion coefficient are in/in/deg F.

I attached a sample spreadsheet in Mathcad 15. The answer should be 0.936in but I cant seem to get that. What am I doing wrong.

David,

for the temperature change, delta T, you need to use the unit "delt degree F", as you did for alpha: degree F by it iself relates to absolute 0 in Kelevin or 256K
