6.6671/°F
That's 171,429× as much as plastic — nothing on our list beats it. A 10 m beam would move about 4,800,000 mm over a 40 °C swing.
What it means
How much does it move?
Linear expansion. Volume expansion is roughly three times the linear figure for solids.

The units
About these units
Per kelvin (1/K)
The raw SI form. Steel is 0.000012 per kelvin, which is why ppm is preferred.
Per degree Fahrenheit (1/°F)
The US form, 1.8 times smaller than the per-kelvin figure.
