Sorry, I was out the past few days because my back decided it was time to remind me that my body is much older than my brain thinks I am.
As mentioned above, the thermal coefficient (more properly known as linear "Coefficient of Thermal Expansion" or CTE), applies in a single direction/axis. So, over a given distance, there is X amount of change (where X is the CTE).
CTE tells you how much change you will see per inch of length, and per degree of temperature change.
So, 6.5 uin/in/F tells you that each inch of length will change by 6.5 micro inches for every degree of change.
If you have a 1 inch length, and change it by 1 degree, then it will change 6.5 micro inches (.0000065").
If you have 10 inch length, and change it by 1 degree, then it will change 6.5 x 10= 65 micro inches (.000065").
If you have 10 inch length, and change it by 10 degrees, then it will change 6.5x10x10= 650 micro inches (.000650")
