How to convert Celsius to Fahrenheit

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

°C × 33.8 = °F

Multiply your celsius value by 33.8 to get fahrenheit. For the reverse, divide by the same factor.
