About this tool
Converting Fahrenheit to Celsius reverses the Celsius-to-Fahrenheit formula: subtract 32, then multiply by 5/9. Because the two scales have different zero points, this offset-then-scale order matters — doing it in the wrong order gives a wrong answer.
Fahrenheit is still used for everyday weather and oven temperatures in the US, while Celsius is standard almost everywhere else and in all scientific work — this converter is built for reading a US weather report, oven dial or thermostat when you think in Celsius.
The reference table below spans a cold winter day up to boiling water, including a typical oven setting, so you can sanity-check a result at a glance.
