Common Temperature Conversions
Celsius to Fahrenheit
The formula is °F = (°C × 9/5) + 32.
°F = (°C × 9/5) + 3271.6°F
Fahrenheit to Celsius
The formula is °C = (°F − 32) × 5/9.
°C = (°F − 32) × 5/9176.7°C (most UK and EU recipes round this to 180°C)
Celsius to Kelvin
The formula is K = °C + 273.15.
K = °C + 273.15293.15 K
Kelvin to Celsius
The formula is °C = K − 273.15.
°C = K − 273.1520°C
Temperature Conversion Questions
What is the formula for Celsius to Fahrenheit?+
°F = (°C × 9/5) + 32. For example, 25°C × 9/5 = 45, and 45 + 32 = 77°F.
What are common Celsius temperatures in Fahrenheit?+
15°C is 59°F, 25°C is 77°F, 30°C is 86°F, 35°C is 95°F and 40°C is 104°F.
What is 37°C in Fahrenheit?+
37°C is 98.6°F, the traditional average adult body temperature. A normal range runs from roughly 36.5°C to 37.5°C (97.7°F to 99.5°F).
What is 40°C in Fahrenheit?+
40°C is 104°F. As body temperature that is a very high fever, and as air temperature it is an extreme heat wave. This page converts numbers and is not medical advice.
What is 180°C in Fahrenheit for baking?+
180°C is 356°F. Most US recipes round it to 350°F. If a recipe says 180°C fan, drop it by about 20°C for a conventional oven.
