Frequently asked questions
How do I convert Celsius to Fahrenheit?
Choose the temperature category, enter the Celsius value and read off the Fahrenheit result. The formula is °F = °C × 9/5 + 32, so 20°C is 68°F. Temperature is the one category where conversion involves an offset, not just multiplication.
