FAQ

자주 묻는 질문

Q1. How do I convert Celsius to Fahrenheit?

The formula is Fahrenheit = Celsius × 9/5 + 32. Pick Celsius as the source and Fahrenheit as the target to calculate it automatically.

Q2. Is temperature conversion different from other units?

Yes. Length and weight just multiply by a ratio, but temperature needs a separate formula involving addition and subtraction between Celsius, Fahrenheit, and Kelvin.

Q3. Why can Kelvin never be negative?

Kelvin is an absolute temperature scale, so its lowest possible value, absolute zero (-273.15°C), is 0K — Kelvin values can never go negative.

Q4. Can I convert negative temperatures?

Yes, enter a negative value and it converts correctly between Celsius, Fahrenheit, and Kelvin.

Q5. Is my input sent to a server?

No. All calculations happen entirely in your browser and are never sent to or stored on a server.
