Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
Multiply Celsius by 9/5 (or 1.8) and add 32. Formula: °F = (°C × 9/5) + 32. For example, 20°C = 68°F.
How do I convert Fahrenheit to Celsius?
Subtract 32 from Fahrenheit and multiply by 5/9. Formula: °C = (°F - 32) × 5/9. For example, 68°F = 20°C.
What is absolute zero?
Absolute zero is 0 Kelvin, -273.15°C, or -459.67°F. It's the lowest possible temperature where all molecular motion stops.
When are Celsius and Fahrenheit equal?
