The converted temperature appears instantly with high precision. The tool may also show the conversion formula used.

Understanding the Conversions

Celsius to Fahrenheit: (°C × 9/5) + 32 = °F

Fahrenheit to Celsius: (°F - 32) × 5/9 = °C

Celsius to Kelvin: °C + 273.15 = K

Kelvin to Celsius: K - 273.15 = °C

Important Temperature Points

• Absolute Zero: -273.15°C = -459.67°F = 0 K
• Water Freezing: 0°C = 32°F = 273.15 K
• Water Boiling: 100°C = 212°F = 373.15 K
• Body Temperature: ~37°C = ~98.6°F = ~310 K
• Room Temperature: ~20°C = ~68°F = ~293 K

Tips for Accurate Conversions

• Remember that Kelvin doesn't use the degree symbol
• Kelvin cannot have negative values (absolute zero is 0 K)
• Use decimals for precise scientific measurements
• The Celsius and Kelvin scales have the same interval size

Frequently Asked Questions

Why are there different temperature scales?

Different temperature scales evolved in different regions and for different purposes. Celsius is metric and used globally, Fahrenheit is traditional in the US, and Kelvin is the absolute scale used in science.

Which temperature scale should I use?

It depends on your context: use Celsius for general international use, Fahrenheit if you're in the US, and Kelvin for scientific calculations, especially in thermodynamics and physics.

What is absolute zero?

Absolute zero (0 K, -273.15°C, -459.67°F) is the theoretical temperature at which all molecular motion stops. It's the lowest possible temperature.

Can temperature be negative in Kelvin?

No, the Kelvin scale starts at absolute zero (0 K) and doesn't have negative values. However, Celsius and Fahrenheit can have negative temperatures.

Why doesn't Kelvin use the degree symbol?

Kelvin is an absolute temperature scale, not a relative one like Celsius and Fahrenheit. By convention, we say "300 kelvins" or "300 K," not "300 degrees Kelvin."

How accurate are the conversions?

Our converter uses the standard conversion formulas and provides results with high precision, suitable for both educational and scientific applications.

What's the relationship between Celsius and Fahrenheit?

The Fahrenheit scale has smaller degrees than Celsius. A change of 1°C equals a change of 1.8°F. The scales also have different zero points (water freezes at 0°C but 32°F).

Why is body temperature 98.6°F if water boils at 212°F?

The human body maintains a temperature around 37°C (98.6°F), which is well below water's boiling point of 100°C (212°F). This temperature is optimal for our biological processes.

Can I use this for oven temperature conversions?

Yes! This is perfect for converting oven temperatures between Celsius and Fahrenheit when using international recipes. For example, 180°C ≈ 356°F (often rounded to 350°F).
