Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. For the reverse: °C = (°F − 32) × 5/9. A quick mental trick: double the Celsius temperature and add 30 for an approximate Fahrenheit value.
What is Kelvin?
Kelvin is the SI base unit of temperature. 0 K is absolute zero — the lowest possible temperature. Kelvin has no negative values. To convert from Celsius: K = °C + 273.15.
What are some key temperature reference points?
Water freezes at 0°C / 32°F / 273.15K. Water boils at 100°C / 212°F / 373.15K. Body temperature is 37°C / 98.6°F. Room temperature is ~20-22°C / 68-72°F.
