Convert linear thermal expansion coefficient between 1/K and 1/°F.
result = value × (from→1/K) ÷ (to→1/K); 1/°F = 1.8 × 1/K
It converts convert linear thermal expansion coefficient between 1/k and 1/°f by first normalising your value to the SI base unit (per kelvin) and then scaling to your chosen target unit. This hub-and-spoke approach guarantees every unit pair is internally consistent.
1.2e-5 /K to 1/°F: 1.2e-5 ÷ 1.8 ≈ 6.67e-6 /°F.
Because the coefficient applies to a temperature DIFFERENCE, not an actual temperature. A change of 1 K equals a change of 1.8 °F, so α in 1/°F = α in 1/K ÷ 1.8. The 32° offset only applies when converting real temperatures, not differences.

Conversions are exact ratios where the units are defined exactly (most SI and imperial units) and best-available constants otherwise. Extremely large or small magnitudes are shown in general (g) format; round-tripping through the base unit may introduce tiny floating-point differences in the final decimal places.
