Converters
Temperature converter
Convert Celsius, Fahrenheit, and Kelvin while seeing all three scales together.
Converts Celsius, Fahrenheit, and Kelvin using their exact scale relationships.
Converted temperature
68 °F
20 °C equals 68 °F.
Celsius20 °C
Fahrenheit68 °F
Kelvin293.15 K
Kelvin values below absolute zero are not physically meaningful, even if entered mathematically.
Plain-language method
Temperature scales have different zeros and intervals.
Celsius and Kelvin use the same interval size but different zero points. Fahrenheit uses both a different zero point and a different interval size.
The tool converts the source temperature to Celsius first, then converts that result to the selected scale.
°F = °C × 9 ÷ 5 + 32 | K = °C + 273.15
