Fahrenheit (°F) is used primarily in the United States, with 32° freezing and 212° boiling. Kelvin (K) is the scientific absolute scale, starting at absolute zero (−273.15°C), and is used in physics, astronomy, and chemistry.

Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. For example, 100°C = (100 × 1.8) + 32 = 212°F. To convert back: °C = (°F − 32) × 5/9.
