To get there, use K = (°F + 459.67) × 5/9. ## Values either side *Degrees Fahrenheit near 18, converted to kelvin.* | Degrees Fahrenheit | Kelvin | | --- | --- | | 14 °F | 263.15 | | 15 °F | 263.7056 | | 16 °F | 264.2611 | | 17 °F | 264.8167 | | 18 °F ← | 265.3722 | | 19 °F | 265.9278 | | 20 °F | 266.4833 | | 21 °F | 267.0389 | | 22 °F | 267.5944 | ## How the conversion works The relationship is K = (°F + 459.67) × 5/9. 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 °F in kelvin? 18 °F is 265.3722 K. ### How do you convert degrees Fahrenheit to kelvin?
