🌡️ Fahrenheit to Kelvin

How to Convert Fahrenheit to Kelvin

To convert Fahrenheit to Kelvin: K = (°F + 459.67) × 5/9. Or you can convert in two steps: first convert °F to °C using (°F − 32) × 5/9, then add 273.15. For example, 98.6°F = (98.6 − 32) × 5/9 + 273.15 = 37 + 273.15 = 310.15 K.

This conversion is most commonly needed in physics and chemistry problems, where temperatures are given in Fahrenheit (common in US textbooks) but need to be expressed in Kelvin for calculations involving the ideal gas law, thermodynamics or astrophysics.
