I may be wrong but I think you refer to the coefficient of linear expansion ....thermal linear expansion...
Explanation:
It is a number that tells us the change of length of an object for a change of
The length considered is relative to the original and so our coefficient gives us the fractional change (=how many times...) of the object with temperature (units of
As you can see in the table above the values are quite small BUT can represent huge effects when, say, you consider the expansion of rails or steel girders.
