System FAQ

How do I convert Celsius to Fahrenheit?

Formula: (°C × 9/5) + 32 = °F. Examples: 0°C = 32°F (freezing), 100°C = 212°F (boiling), 37°C = 98.6°F (body temperature), 20°C = 68°F (room temperature).

How do I convert Fahrenheit to Celsius?

Formula: (°F - 32) × 5/9 = °C. Examples: 32°F = 0°C, 98.6°F = 37°C, 68°F = 20°C, 212°F = 100°C.

What temperature is 37°C in Fahrenheit?

37°C = 98.6°F — this is normal human body temperature. A fever is generally considered 38°C (100.4°F) or above.

What is Kelvin and how does it relate to Celsius?

Kelvin is the scientific temperature scale where 0K = absolute zero (the coldest possible temperature). To convert Celsius to Kelvin, add 273.15. So 0°C = 273.15K, 100°C = 373.15K.

What temperature should I bake a cake?

Most cakes bake at 350°F (175°C). For reference: 325°F = 163°C, 375°F = 191°C, 400°F = 204°C, 425°F = 218°C. Use this converter to adapt recipes between US (Fahrenheit) and European (Celsius) measurements.
