FAQ
How do Celsius and Fahrenheit convert?
Fahrenheit = Celsius × 9/5 + 32. For example, 25°C is 77°F.

Not physically — zero Kelvin is absolute zero. The converter still performs the math without enforcing physical limits.
Are Rankine or other scales supported?
Only Celsius, Fahrenheit and Kelvin, the three most common temperature scales.
