Convert Percent per kelvin to Per kelvin
Convert Percent per kelvin (%/K) to Per kelvin (1/K) instantly and accurately.
Conversion Formula
1/K = %/K × 0.01
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.
About Per kelvin
The per kelvin (1/K = K⁻¹) is the SI unit for linear thermal expansion coefficient (α = (1/L) dL/dT). Used in NIST databases, FEA material cards, and thermodynamics textbooks. Liquid mercury: ≈6.1 × 10⁻⁵ /K; aluminium: ≈2.3 × 10⁻⁵ /K; fused silica: ≈5.5 × 10⁻⁷ /K. 1 /K = 10⁶ ppm/K = 1/°C.
