Good to know
Oven recipes often use Fahrenheit: 350 °F is about 177 °C, usually rounded to 180 °C. A fever is generally a temperature of 100.4 °F (38 °C) or higher.
How to convert degrees Fahrenheit to degrees Celsius
Temperature scales have different zero points, so you cannot simply multiply. Use this formula:
°C = (°F − 32) × 5/9
Worked examples
- 0 °F = -17.77778 °C
- 32 °F = 0 °C
- 98.6 °F = 37 °C
- 350 °F = 176.6667 °C
