How to convert Celsius to Fahrenheit

Enter a temperature in °C and the °F value appears instantly, along with the step-by-step working, the Kelvin value and a mental-math estimate. Use it for weather abroad, a European recipe in an American oven, or a thermometer set to Celsius.

Celsius to Fahrenheit formula

°F = °C × 9/5 + 32 = °C × 1.8 + 32

Between freezing (0 °C = 32 °F) and boiling (100 °C = 212 °F) there are 100 Celsius degrees and 180 Fahrenheit degrees, so each °C is 1.8 °F, and the scales are offset by 32. Example: 25 °C → 25 × 1.8 = 45 → 45 + 32 = 77 °F.

Body temperature and fever

The classic "normal" body temperature of 98.6 °F is 37 °C; many people actually run slightly lower, around 36.5 °C (97.7 °F). US health agencies such as the CDC commonly use 100.4 °F (38 °C) as the fever threshold. Readings vary by method — oral, ear, forehead and armpit can differ by about half a degree Celsius.

Oven temperatures

US recipes give oven temperatures in 25 °F steps (325, 350, 375, 400 °F). When converting a Celsius recipe, round to the nearest step: 180 °C = 356 °F → 350 °F, and 200 °C = 392 °F → 400 °F. Many recipes written for fan (convection) ovens use about 20 °C (25 °F) lower than conventional ovens, so check which one the recipe assumes.

Mental math

Double it and add 30. 20 °C → 70 °F (exact 68), 30 °C → 90 °F (exact 86). It is most accurate around 10 °C and overestimates more at higher temperatures, so use the real formula for oven temperatures.

Converting a temperature change

"5 °C warmer than yesterday" is 5 × 1.8 = 9 °F warmer — do not add 32. Only add 32 when converting an actual temperature reading, not a difference.

Body temperature references are general information, not medical advice. If you have a fever, follow your healthcare provider's guidance.

FAQ

What is 37 °C in Fahrenheit?
37 × 1.8 + 32 = 98.6 °F, the classic normal body temperature.
What is 180 °C in Fahrenheit for baking?
180 °C is 356 °F. In a US oven, set 350 °F.
What is 38 °C in Fahrenheit?
Exactly 100.4 °F, the temperature commonly used as the fever threshold in the US.
Is 20 °C hot or cold?
20 °C is 68 °F — mild and pleasant, about normal room temperature.
What is the easiest way to convert Celsius to Fahrenheit?
Double the Celsius number and add 30. It is within a few degrees for everyday weather; for exact results use °F = °C × 1.8 + 32.
