Multiply the Celsius temperature by 9/5, then add 32. For example, 20°C × 9/5 + 32 = 68°F. To convert back, subtract 32 and multiply by 5/9.
37°C is equal to 98.6°F. This is normal human body temperature.
Celsius and Fahrenheit are equal at −40 degrees. This is the only point where both scales give the same reading.
Absolute zero is −273.15°C, or 0 Kelvin. It is the lowest possible temperature — the point at which all molecular motion stops.
The United States is the main country that uses Fahrenheit for everyday temperature. Most other countries, including the UK, Australia and all of Europe, use Celsius. Kelvin is used internationally in science.
