Key Formulas
Celsius → Fahrenheit
°F = f(°C)Fahrenheit → Celsius
°C = f(°F)Celsius → Kelvin
K = f(°C)Kelvin → Celsius
°C = f(K)Formula
°F = (°C × 1.8) + 32Celsius and Fahrenheit measure temperature with different zero points and interval sizes: a change of 1°C equals a change of 1.8°F, while 0°C corresponds to 32°F. This conversion is useful when an oven, weather forecast, vehicle display, or thermometer uses a different scale from the one you normally read.

Frequently Asked Questions
Real-World Examples
A recipe gives an oven setting of 180°C, but the oven control displays Fahrenheit. The mathematical conversion is 356°F; an oven may require selecting the nearest available setting.
180 °C = 356 °F
A thermometer records 38.5°C and the reading must be entered in a system that expects Fahrenheit.
38.5 °C = 101.3 °F
A traveler converts a 25°C weather forecast to 77°F before deciding what to wear.
25 °C = 77 °F
A dashboard shows an outside temperature of −5°C, and the driver wants the equivalent 23°F reading.
-5 °C = 23 °F
