What's the difference between Celsius, Fahrenheit, and Kelvin?

Celsius (°C) is the metric scale with water freezing at 0°C. Fahrenheit (°F) is used mainly in the US with freezing at 32°F. Kelvin (K) is the absolute temperature scale used in science, starting at -273.15°C (absolute zero).

Can I use Temperature Converter on my phone?

Yes, works perfectly on all devices including iPhone, Android, iPad, and desktop browsers. The tool is fully responsive with a mobile-optimized interface.

Is my temperature data stored or tracked?

No. All conversions happen instantly in your browser. No data is sent to servers, stored, or tracked. Your privacy is completely protected.

What is absolute zero and why does it matter?

Absolute zero is -273.15°C (0 Kelvin), the lowest possible temperature where all molecular motion stops. The converter won't accept temperatures below this scientific limit.

Can I convert negative temperatures?

Yes, the converter handles negative temperatures in Celsius and Fahrenheit. However, negative Kelvin values are physically impossible and will display an error message.

Why would I need to convert to Kelvin?

Kelvin is the standard unit in science, physics, and chemistry because it's an absolute temperature scale. It's essential for scientific calculations, gas laws, and laboratory work.
