Percent per kelvin (%/K)

Conversion Formula

%/K = 1/°C × 100

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.

About Percent per kelvin

The %/K equals exactly 10⁻² /K = 10 000 ppm/K and is used for high-CTE materials such as polymers, foams, and rubber. PTFE: ≈0.0135 %/K; HDPE: ≈0.015 %/K; natural rubber: ≈0.06 %/K; silicone rubber: ≈0.10 %/K. 1 %/K = 10⁻² /K = 10 mm/(m·K) = 10 000 ppm/K.
