How to convert degrees Fahrenheit to kelvins
Physics and chemistry problems that start from US temperatures; Kelvin never goes below zero.
To convert degrees Fahrenheit to kelvins, use K = (°F − 32) × 5/9 + 273.15. Temperature scales have different zero points, so the conversion adds an offset as well as scaling — multiplying alone gives the wrong answer.
Fahrenheit (°F): °C × 9/5 + 32. Kelvin (K): SI base unit; 0 K is absolute zero.
For the opposite direction, use the Kelvin to Fahrenheit converter. All temperature units are on the temperature converter.
Limitations
- Results are rounded to the decimal places you choose; the calculation itself keeps full precision.
