Formula • Worked example • Interpretation
Temperature scales differ in both their zero points and, sometimes, degree sizes. Unlike simple distance conversion, most temperature conversions need an offset.
68°F = 20°C = 293.15 K.
A temperature difference of 1°C equals a difference of 1 K, but absolute Celsius and Kelvin readings are offset by 273.15.
For cooking, verify whether the oven uses Fahrenheit or Celsius before setting the temperature.
Kelvin temperatures below 0 K are outside ordinary thermodynamic temperature definitions. Check whether you are converting absolute temperatures or temperature differences.
