Formula
°C → °F : F = C × 9/5 + 32
°F → °C : C = (F − 32) × 5/9
°C → K : K = C + 273.15
°F → K : K = (F − 32) × 5/9 + 273.15
K → °C : C = K − 273.15Example
Input: 100 °C
Result: 212 °F / 373.15 K
FAQ
Absolute zero is 0 K = −273.15 °C = −459.67 °F. It is the lowest possible temperature where all molecular motion stops.
−40 °C equals −40 °F. That is the only point where both scales have the same value.
Normal body temperature is approximately 37 °C (98.6 °F / 310.15 K).
