How to convert Fahrenheit degree intervals to kelvin intervals
A change of 1 kelvin equals 1 Celsius degree or 1.8 Fahrenheit degrees. No 32 or 273.15 offset belongs in an interval conversion. Negative intervals represent cooling.
Use x for the value in Δ°F, b for the intermediate value in ΔK, and y for the result in ΔK.
ΔK = Δ°F × 0.5555555555555556
Worked examples
10 Δ°F ≈ 5.55555555556 ΔK
Step 1: (10 × 0.555555555556) ≈ 5.55555555556 ΔK.
Step 2: 5.55555555556 ÷ 1 ≈ 5.55555555556 ΔK.20 Δ°F ≈ 11.1111111111 ΔK
Step 1: (20 × 0.555555555556) ≈ 11.1111111111 ΔK.
Step 2: 11.1111111111 ÷ 1 ≈ 11.1111111111 ΔK.
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 Fahrenheit degree intervals
Fahrenheit degree intervals (Δ°F) measures temperature interval under the conventions above. The base value in ΔK is (x × 0.555555555556), where x is the numerical value in Δ°F. Factors shown here are rounded for display; calculations use the stored factor.
About Kelvin intervals
Kelvin intervals (ΔK) measures temperature interval under the conventions above. The base value in ΔK is (x × 1), where x is the numerical value in ΔK. Factors shown here are rounded for display; calculations use the stored factor.
