Frequently Asked Questions
- °F = (°C × 9/5) + 32. Alternatively: °F = (°C × 1.8) + 32.
- Celsius and Fahrenheit are equal at −40 degrees (−40°C = −40°F).
- 37°C = (37 × 9/5) + 32 = 66.6 + 32 = 98.6°F. This is normal human body temperature.
- 72°F = (72 − 32) × 5/9 = 40 × 5/9 = 22.2°C. This is a common comfortable room temperature.
- 180°C = (180 × 9/5) + 32 = 324 + 32 = 356°F. Standard baking temperature for cakes.
