How to convert Fahrenheit to Celsius
Temperature is measured on three main scales: Celsius (used worldwide), Fahrenheit (used in the United States), and Kelvin (used in science). Unlike most conversions, temperature uses an offset as well as a multiplier.
Fahrenheit to Celsius: subtract 32, then multiply by 5/9. Celsius to Kelvin: add 273.15. The scales intersect at -40°, where -40°C equals -40°F.
Formula
°F × -17.2222222222 = °C
Multiply your fahrenheit value by -17.2222222222 to get celsius. For the reverse, divide by the same factor.
