How the Calculation Works (Affine Transformation)
Formula:
K = (°F - 32) × 5/9 + 273.15
Substitution:(1 - 32) × 5/9 + 273.15
Calculated Result:255.9278 K
Convert Fahrenheit to Celsius by subtracting 32 and multiplying by 5/9, then add 273.15 to reach Kelvin.

華氏度 (°F)
The Fahrenheit scale sets 32 °F as the freezing point of water and 212 °F as the boiling point at standard atmospheric pressure, with 180 equal divisions between them.
ケルビン (K)
The kelvin is the SI base unit of thermodynamic temperature. It is defined by setting the Boltzmann constant to exactly 1.380649 × 10⁻²³ J/K. 0 K is absolute zero.
