μin/(in·°F) = %/K × 5555.555556

About Percent per kelvin

The %/K equals exactly 10⁻² /K = 10 000 ppm/K and is used for high-CTE materials such as polymers, foams, and rubber. PTFE: ≈0.0135 %/K; HDPE: ≈0.015 %/K; natural rubber: ≈0.06 %/K; silicone rubber: ≈0.10 %/K. 1 %/K = 10⁻² /K = 10 mm/(m·K) = 10 000 ppm/K.

About Microinches per inch per degree Fahrenheit

The microinch per inch per degree Fahrenheit (μin/(in·°F)) equals exactly 9/5 × 10⁻⁶ /K = 1 ppm/°F. It is the native US CTE unit in ASTM E228 and ASTM E831 standards; most US material datasheets list CTE values in this unit. Steel: ≈6.7 μin/(in·°F); aluminium: ≈12.8 μin/(in·°F); titanium: ≈4.9 μin/(in·°F). 1 μin/(in·°F) = 1 ppm/°F.
