What is Temperature Conversion?

Temperature conversion is the process of changing the value of temperature from one unit of measurement to another. The most common temperature scales are Celsius, Fahrenheit, and Kelvin. Whether you are traveling, cooking, or conducting science experiments, this converter helps you seamlessly translate values across these scales.

Common Temperature References

  • Water freezes: 0°C / 32°F / 273.15 K
  • Room temperature: ~20–25°C / ~68–77°F / 293–298 K
  • Average body temperature: ~37°C / ~98.6°F / 310.15 K
  • Water boils: 100°C / 212°F / 373.15 K

Temperature Conversion Formulas

For reference, here are the standard formulas used for temperature conversions:

  • Celsius to Fahrenheit: (°C × 9/5) + 32
  • Fahrenheit to Celsius: (°F − 32) × 5/9
  • Celsius to Kelvin: °C + 273.15
  • Kelvin to Celsius: K − 273.15
  • Fahrenheit to Kelvin: (°F − 32) × 5/9 + 273.15
  • Kelvin to Fahrenheit: (K − 273.15) × 9/5 + 32

Frequently Asked Questions

Our temperature converter uses exact, universally accepted scientific formulas for conversions, ensuring absolute precision. Results are typically rounded to 2 decimal places for better readability, removing unnecessary trailing zeros.

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8) and then add 32. The formula is: (°C × 9/5) + 32.

Yes, you can convert negative temperatures for both Celsius and Fahrenheit. However, remember that Kelvin is an absolute scale, meaning it cannot go below 0 K (absolute zero).
