How to Convert Fahrenheit to Kelvin
To convert Fahrenheit to Kelvin, subtract 32, multiply by 5/9, then add 273.15. For example, 72°F: (72 − 32) × 5/9 + 273.15 = 40 × 0.5556 + 273.15 = 295.37 K. This two-step process first converts to Celsius, then shifts to the Kelvin scale.
Worked Example: Convert 32 °F to K
Start with the value in fahrenheit
32 °F
Apply the formula
K = (32 − 32) × 5/9 + 273.15
Calculate the result
32 °F = 273.15 K
