How It Works
Enter a temperature value in Celsius, Fahrenheit, or Kelvin, and the tool instantly calculates and displays the equivalent in the other two units. The conversion uses standard temperature formulas: C to F = (C × 9/5) + 32, F to C = (F - 32) × 5/9, K to C = K - 273.15. Common temperature references are shown (water freezing/boiling points, body temperature, absolute zero) for context. Perfect for cooking, science, weather, international travel, or educational purposes. All calculations happen instantly in your browser.
Frequently Asked Questions
What temperature units are supported?
Celsius (°C), Fahrenheit (°F), and Kelvin (K). Enter a value in any unit to see conversions to all others.
What's the formula for Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. For example, 0°C = 32°F, 100°C = 212°F.
What's absolute zero?
Absolute zero is 0 Kelvin = -273.15°C = -459.67°F. The coldest possible temperature.
Can I use decimal values?
Yes! Enter any decimal value for precise conversions (e.g., 98.6°F for body temperature).
Why use Kelvin?
Kelvin is the SI unit for temperature, commonly used in science. It starts at absolute zero (no negative values).
