The three temperature scales
Celsius is the everyday metric scale (water freezes at 0°, boils at 100°), Fahrenheit is common in the US (32° and 212°), and Kelvin is the scientific absolute scale starting at absolute zero. Because the scales have different zero points, conversions are affine — not just a simple ratio — which this converter handles for you.
