Conversion Formula
μin/(in·°F) = 1/°C × 555555.5556
About Per degree Celsius
The per degree Celsius (1/°C = °C⁻¹) equals exactly 1/K since temperature intervals 1 °C = 1 K (exact). Common in European and ISO standards, chemistry textbooks, and physics literature as an alternative notation for the SI unit 1/K. A material with α = 12 × 10⁻⁶ /K is identically expressed as 12 × 10⁻⁶ /°C. 1 /°C = 1 /K = 10⁶ 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.
