To get there, use °F = K × 9/5 − 459.67. ## Values either side *Kelvin near 18, converted to degrees Fahrenheit.* | Kelvin | Degrees Fahrenheit | | --- | --- | | 14 K | -434.47 | | 15 K | -432.67 | | 16 K | -430.87 | | 17 K | -429.07 | | 18 K ← | -427.27 | | 19 K | -425.47 | | 20 K | -423.67 | | 21 K | -421.87 | | 22 K | -420.07 | ## How the conversion works The relationship is °F = K × 9/5 − 459.67. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor. ## Common questions ### What is 18 K in degrees Fahrenheit? 18 K is -427.27 °F. ### How do you convert kelvin to degrees Fahrenheit?
