Convert Per degree Celsius to Per degree Fahrenheit
Convert Per degree Celsius (1/°C) to Per degree Fahrenheit (1/°F) instantly and accurately.
Conversion Formula
1/°F = 1/°C × 0.5555555556
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 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).
