Frequently asked questions
How do you convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 (that is, 1.8) and add 32. For example, 20°C × 1.8 = 36, plus 32 = 68°F. To go the other way, subtract 32 first, then multiply by 5/9.
What is Kelvin and how does it relate to Celsius?
Kelvin is the scientific temperature scale that starts at absolute zero, the coldest possible temperature. It uses the same size degree as Celsius, so you convert simply by adding 273.15 to a Celsius value, or subtracting it to go back.
What is a normal body temperature in Fahrenheit?
The standard reference is 37°C, which is 98.6°F. Normal readings vary a little by person and time of day, roughly 36.1–37.2°C (97–99°F).
