Inverse Kelvin
Explanation:
We know the definition of the areal expansion coefficient:
Doing unit analysis (in any system with L being a length,
Since the SI unit for temperature is Kelvin, the unit for the areal expansion coefficient is
If we were also really tricky, we could notice that the expansion coefficient can be written as
which obviously has units of
