About Millimetres per metre per degree Celsius

The millimetre per metre per degree Celsius (mm/(m·°C)) equals exactly 10⁻³ /K = 1 mm/(m·K), since temperature intervals 1 °C = 1 K (exact). Used in European structural engineering, EN standards, and civil/mechanical design codes for expansion joint sizing. Steel rail: 0.012 mm/(m·°C); aluminium curtain wall: 0.023 mm/(m·°C). 1 mm/(m·°C) = 10⁻³ /K = 1 mm/(m·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).
