To get there, use °F = °C × 9/5 + 32. ## Values either side *Degrees Celsius near 18, converted to degrees Fahrenheit.* | Degrees Celsius | Degrees Fahrenheit | | --- | --- | | 14 °C | 57.2 | | 15 °C | 59 | | 16 °C | 60.8 | | 17 °C | 62.6 | | 18 °C ← | 64.4 | | 19 °C | 66.2 | | 20 °C | 68 | | 21 °C | 69.8 | | 22 °C | 71.6 | ## How the conversion works The relationship is °F = °C × 9/5 + 32. 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 °C in degrees Fahrenheit? 18 °C is 64.4 °F. ### How do you convert degrees Celsius to degrees Fahrenheit?
