Formulas
- °C = (°F − 32) × 5/9
- °F = °C × 9/5 + 32
- K = °C + 273.15
Examples
- 20 °C = 68 °F — a comfortable room temperature.
- 180 °C (a common oven setting in European recipes) = 356 °F, in practice 350–360 °F.
- 37 °C = 98.6 °F — normal body temperature.
- −40 °C = −40 °F — the only point where the scales meet.
FAQ
Quick mental conversion from Celsius to Fahrenheit? Double it and add 30: 25 °C → about 80 °F (exactly 77 °F). For ovens, the oven temperature converter also covers gas marks.
What’s absolute zero? 0 K = −273.15 °C = −459.67 °F — nothing can be colder.
