About Millimetres per metre per degree Fahrenheit

The mm/(m·°F) equals 9/5 × 10⁻³ /K ≈1.8 × 10⁻³ /K, combining metric displacement with Fahrenheit temperature. It appears in US-origin pipeline and structural reports where dimensions are given in metres but temperatures in °F. Steel: ≈0.00667 mm/(m·°F); aluminium: ≈0.01283 mm/(m·°F). 1 mm/(m·°F) = 9/5 × 10⁻³ /K.

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).
