Fahrenheit to Kelvin Converter
Convert any temperature from Fahrenheit (°F) to Kelvin (K). Uses the formula K = (°F − 32) × 5/9 + 273.15.
Formula
K = (°F − 32) × 5/9 + 273.15
How to Convert Fahrenheit to Kelvin
Subtract 32 from the Fahrenheit value, multiply by 5/9, then add 273.15 to get Kelvin.
Example: Convert 72°F to Kelvin
K = (72 − 32) × 5/9 + 273.15 = 40 × 0.5556 + 273.15 = 295.37 K
K = (72 − 32) × 5/9 + 273.15 = 40 × 0.5556 + 273.15 = 295.37 K
