About this tool
To convert Fahrenheit to Celsius, subtract 32 first (that aligns the zero points — water freezes at 32 °F and 0 °C), then multiply by 5/9 to adjust for the different step size. US weather, ovens and fever readings all arrive in Fahrenheit; most of the world thinks in Celsius.
Useful anchors: 68 °F = 20 °C (room temperature), 86 °F = 30 °C (a hot day), 101 °F = 38.3 °C (a fever), and 350 °F = 176.7 °C (a standard baking temperature).
How to use it
