Temperature Converter
Convert between Celsius, Fahrenheit and Kelvin.
About Temperature Converter
The GuruAlpha Temperature Converter converts between Celsius, Fahrenheit and Kelvin instantly. Enter a temperature in any scale and see the equivalent in all three. Includes a visual thermometer display and common temperature reference points. Essential for cooking, weather, science and international travel.
Temperature conversion is one of the most frequently needed unit conversions. Cooking recipes use different temperature scales in different countries. Weather forecasts display temperatures in different scales depending on the region. Scientific calculations often require Kelvin. The Temperature Converter handles all three scales with accurate, instant results.
The converter supports three temperature scales: Celsius (°C) — used by most of the world, Fahrenheit (°F) — used in the United States, and Kelvin (K) — used in science (0 K = absolute zero). The conversion formulas are: °F = (°C × 9/5) + 32, °C = (°F - 32) × 5/9, K = °C + 273.15.
The visual thermometer display shows the temperature on a mercury thermometer graphic, with the scale visible for context. This visual representation helps users intuitively understand the temperature rather than just seeing numbers. Key reference points are marked: water freezing (0°C/32°F), body temperature (37°C/98.6°F), water boiling (100°C/212°F).
For cooking, the converter is essential for following international recipes. A recipe calling for 180°C needs to be set to 356°F on an American oven. The converter makes this instant, preventing the common mistake of setting the wrong temperature and ruining a dish.

Tips for Using Temperature Converter
- 180°C = 356°F — the most common baking temperature conversion.
- Body temperature is 37°C / 98.6°F / 310.15 K.
- Water boils at 100°C / 212°F / 373.15 K.
- Use Kelvin for scientific calculations — 0 K is absolute zero.
- For cooking, always convert to your oven's scale before preheating.
Frequently Asked Questions About Temperature Converter
What is Kelvin used for?
Kelvin is the SI unit of temperature used in science. 0 K is absolute zero (no molecular motion). It is used in thermodynamics, physics and chemistry.
What is the freezing point of water?
0°C = 32°F = 273.15 K. This is the standard reference point for temperature scales.
Is there a quick way to estimate C to F?
Double the Celsius and add 30 for a rough estimate. Exact: °F = (°C × 9/5) + 32.
Can I convert body temperature?
Yes. Normal body temperature is approximately 37°C / 98.6°F / 310.15 K. Fevers are typically above 38°C / 100.4°F.
