How to convert Per Fahrenheit degree to per kelvin
Choose a coefficient for the same physical quantity: linear, area, and volumetric expansion coefficients are not interchangeable. Per Fahrenheit degree converts with the reciprocal interval factor.
Use x for the value in °F⁻¹, b for the intermediate value in K⁻¹, and y for the result in K⁻¹.
K⁻¹ = °F⁻¹ × 1.8
Worked examples
10 °F⁻¹ ≈ 18 K⁻¹
Step 1: (10 × 1.8) ≈ 18 K⁻¹.
Step 2: 18 ÷ 1 ≈ 18 K⁻¹.20 °F⁻¹ ≈ 36 K⁻¹
Step 1: (20 × 1.8) ≈ 36 K⁻¹.
Step 2: 36 ÷ 1 ≈ 36 K⁻¹.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Per Fahrenheit degree
Per Fahrenheit degree (°F⁻¹) measures thermal expansion under the conventions above. The base value in K⁻¹ is (x × 1.8), where x is the numerical value in °F⁻¹. Factors shown here are rounded for display; calculations use the stored factor.
About Per kelvin
Per kelvin (K⁻¹) measures thermal expansion under the conventions above. The base value in K⁻¹ is (x × 1), where x is the numerical value in K⁻¹. Factors shown here are rounded for display; calculations use the stored factor.
