About Fahrenheit and Kelvin
Converting Fahrenheit to Kelvin uses the formula K = (°F − 32) × 5/9 + 273.15. This two-step conversion first converts Fahrenheit to Celsius, then adds 273.15 to reach absolute Kelvin. Water freezes at 32°F = 273.15 K, body temperature (98.6°F) is 310.15 K, and water boils at 212°F = 373.15 K. This conversion is essential in thermodynamics equations (like the ideal gas law PV=nRT) where temperature must be in Kelvin. American scientists and engineers using Fahrenheit instruments must convert to Kelvin for physics and chemistry calculations.
