About Per kelvin
The per kelvin (1/K = K⁻¹) is the SI unit for linear thermal expansion coefficient (α = (1/L) dL/dT). Used in NIST databases, FEA material cards, and thermodynamics textbooks. Liquid mercury: ≈6.1 × 10⁻⁵ /K; aluminium: ≈2.3 × 10⁻⁵ /K; fused silica: ≈5.5 × 10⁻⁷ /K. 1 /K = 10⁶ ppm/K = 1/°C.
About Percent per degree Fahrenheit
The %/°F equals 9/5 × 10⁻² /K ≈ 0.018 /K, the Fahrenheit percent-expansion unit used in US polymer and rubber industry specifications. PTFE: ≈0.0075 %/°F; HDPE: ≈0.0083 %/°F; silicone rubber: ≈0.056 %/°F. 1 %/°F = 9/5 × 10⁻² /K ≈1.8 %/K.
