Per kelvin (1/K)

Conversion Formula

1/K = 1/°C × 1

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 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.
