Convert Millimetres per metre per degree Celsius to Per degree Celsius
Convert Millimetres per metre per degree Celsius (mm/(m·°C)) to Per degree Celsius (1/°C) instantly and accurately.
Conversion Formula
1/°C = mm/(m·°C) × 0.001
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 Celsius
The per degree Celsius (1/°C = °C⁻¹) equals exactly 1/K since temperature intervals 1 °C = 1 K (exact). Common in European and ISO standards, chemistry textbooks, and physics literature as an alternative notation for the SI unit 1/K. A material with α = 12 × 10⁻⁶ /K is identically expressed as 12 × 10⁻⁶ /°C. 1 /°C = 1 /K = 10⁶ ppm/K.
