About the ppm per degree fahrenheit
The ppm per degree fahrenheit (ppm/°F) is a Imperial unit of thermal expansion.
About the ppm per degree celsius
The ppm per degree celsius (ppm/°C) is a Metric unit of thermal expansion. The usual data-sheet unit; identical to µm per meter per °C.
Where this conversion is used
Converting ppm per degree fahrenheit to ppm per degree celsius comes up when precision machining, bridge and rail design, and optics mounting. Because a Fahrenheit degree is smaller than a Celsius one, a per-°F coefficient is always 1.8 times the per-°C value.
