How to convert kelvin to fahrenheit

°F = (K − 273.15) × 9/5 + 32

Temperature scales have different zero points, so converting needs an offset as well as a scale factor. 300 K becomes 80.33 °F. A handy check: −40 is the same in Celsius and Fahrenheit, and body temperature is about 37 °C or 98.6 °F.
