Temperature Converter
Unlike most units, temperature scales don't share a simple multiplier, so converting by hand means remembering different formulas for each pair. This tool shows Celsius, Fahrenheit and Kelvin all at once, updating live as you type.

How to Use This Tool
- Enter a temperature value.
- Choose which scale you entered it in.
- Read the equivalent in all three scales at once.
Formula
Celsius to Fahrenheit: F = C × 9/5 + 32
Fahrenheit to Celsius: C = (F − 32) × 5/9
Celsius to Kelvin: K = C + 273.15

Frequently Asked Questions
What is 0°C in Fahrenheit and Kelvin?
0°C equals 32°F and 273.15 K.
Why does Kelvin never go negative?
Kelvin is an absolute temperature scale starting at absolute zero (0 K = -273.15°C), the theoretical coldest possible temperature, so negative Kelvin values do not occur in classical physics.
