Ppm per kelvin to ppm per degree Fahrenheit
Type a value in ppm/K to get it in ppm/°F instantly.
6.667ppm/°F
That's about the same as steel. A 10 m beam would move about 4.8 mm over a 40 °C swing.
Convert the other way: ppm/°F to ppm/K
What it means
How much does it move?
Linear expansion. Volume expansion is roughly three times the linear figure for solids.
The math
How to convert ppm/K to ppm/°F
To convert ppm per kelvin to ppm per degree Fahrenheit, multiply by 0.555556.
Example: 12 ppm/K × 0.555556 = 6.66667 ppm/°F.
In the other direction, 1 ppm/°F = 1.8 ppm/K.
