The formula
First convert to Celsius, then add 273.15: K = (°F − 32) × 5/9 + 273.15. Example: 98.6 °F → 37 °C → 310.15 K.
Quick conversion table
| Fahrenheit | Kelvin | Note |
|---|---|---|
| 32 °F | 273.15 K | Water freezes |
| 68 °F | 293.15 K | Room temperature |
| 98.6 °F | 310.15 K | Body temperature |
| 212 °F | 373.15 K | Water boils |
| −459.67 °F | 0 K | Absolute zero |
Physics numericals
Indian students meet Fahrenheit mainly in two places: old thermometers and US weather reports during storm season. Physics numericals sometimes give data in °F and ask for kelvin — this two-step formula handles it without mistakes.
Frequently asked questions
How do you convert fahrenheit to kelvin?
K = (°F − 32) × 5/9 + 273.15.
What is 98.6°F in kelvin?
310.15 K — normal human body temperature.
What is 32°F in kelvin?
273.15 K, the freezing point of water.
Why 273.15?
That is how far absolute zero sits below water's freezing point on the Celsius scale.
