Fahrenheit → Celsius at a glance

NOAA and many US ovens still quote Fahrenheit first. Subtracting 32 shifts the Fahrenheit zero to line up with Celsius ice-point math; multiplying by 5/9 shrinks each Fahrenheit “step” onto the Celsius scale where water boils at one hundred degrees.

Formula you are using

°C = (°F − 32) × 5/9

The inverse is °F = (°C × 9/5) + 32—type in either box and the other column keeps pace.

  • Fahrenheit to Celsius Formula: The Quickest Way to Convert

    To convert Fahrenheit to Celsius, use the formula **C = (F − 32) × 5/9**, where F is the temperature in Fahrenheit. First subtract 32 from the Fahrenheit value, then multiply the result by 5/9 to get Celsius. This is the quickest and most commonly used method for temperature conversion.
