What is temperature difference?
A temperature difference, or interval, is how much a temperature changes, not the temperature itself. Converting a difference is simpler than converting a temperature because the zero points of the scales do not matter: a rise of 1 °C is a rise of 1 K, and a rise of 1.8 °F.
This matters more often than you might think. If a forecast says it will be 10 degrees warmer tomorrow, that is 10 °C = 18 °F warmer, not 50 °F. Engineering quantities such as specific heat capacity (J/kg·K) and thermal expansion (per K) also use temperature differences.
To convert an actual temperature reading, such as 25 °C, use the temperature converter.

Frequently asked questions
Is a change of 1 °C the same as 1 K?
Yes. The Celsius degree and the kelvin are the same size, so a change of 1 °C is a change of 1 K.
How many Fahrenheit degrees is a change of 1 Celsius degree?
A change of 1 °C equals a change of 1.8 °F. Do not add 32: the offset only applies to actual temperatures.
What is 2 °C of global warming in Fahrenheit?
A warming of 2 °C is a warming of 3.6 °F.
