About Per degree Fahrenheit

The per degree Fahrenheit (1/°F = °F⁻¹) equals exactly 9/5 /K = 1.8 /K and is the imperial counterpart of the SI unit. Found in ASME boiler and pressure vessel codes, ASHRAE engineering tables, and UL material data sheets. Iron: ≈6.7 × 10⁻⁶ /°F; ordinary glass: ≈4.9 × 10⁻⁶ /°F. 1 /°F = 9/5 /K (= 1/°R).

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.
