FAQ
- What formula converts Celsius to Fahrenheit?
- °F = °C × 9/5 + 32. For example, 20°C equals 68°F.
- Why does Kelvin matter?
- Kelvin is the SI base unit of temperature used in science. 0 K is absolute zero, which is -273.15°C.
- Is negative Kelvin valid?
- No. Temperatures below absolute zero are physically impossible, so the tool flags such inputs.
