About Temperature Converter

The Temperature Converter tool allows you to convert temperature values between Celsius, Fahrenheit, and Kelvin scales. It's a practical utility for scientific calculations, cooking, weather comparisons, and international communication.

How to Use the Temperature Converter
  1. Enter a temperature value in any of the input fields (Celsius, Fahrenheit, or Kelvin).
  2. As soon as you enter a value in one field, the corresponding values in the other scales will automatically update.
  3. Alternatively, use the slider to adjust the temperature and see real-time conversions.
  4. Click the "Reset" button to clear all fields and start over.
Temperature Scales Explained
  • Celsius (°C): The metric temperature scale where water freezes at 0°C and boils at 100°C at standard atmospheric pressure. Used in most countries worldwide.
  • Fahrenheit (°F): Temperature scale where water freezes at 32°F and boils at 212°F at standard atmospheric pressure. Primarily used in the United States.
  • Kelvin (K): The SI base unit of temperature, used primarily in scientific contexts. 0K represents absolute zero, the theoretical lowest possible temperature. Note that Kelvin doesn't use the degree symbol.
Conversion Formulas
  • Celsius to Fahrenheit: °F = (°C × 9/5) + 32
  • Fahrenheit to Celsius: °C = (°F - 32) × 5/9
  • Celsius to Kelvin: K = °C + 273.15
  • Kelvin to Celsius: °C = K - 273.15
  • Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15
  • Kelvin to Fahrenheit: °F = (K - 273.15) × 9/5 + 32
Common Uses for Temperature Conversion
  • Converting weather forecasts when traveling internationally
  • Following recipes from different regions with different measurement standards
  • Scientific calculations and experiments
  • Converting body temperature readings between scales
  • Educational purposes for learning about temperature scales
  • Industrial and manufacturing processes that specify temperatures
