About the Temperature Converter
Temperature scales trip people up because, unlike length or weight, they don't share a zero point — you can't just multiply. The AlarmDaddy Temperature Converter handles the maths for you between Celsius, Fahrenheit and Kelvin, whether you're following a recipe, reading a weather forecast, or working through a science problem.
Type a temperature, choose the scales, and see the converted value plus the reading on every scale at once.

The formula
Conversions go via Celsius. Fahrenheit to Celsius subtracts 32 then multiplies by 5/9; Kelvin to Celsius subtracts 273.15. The reverse formulas convert Celsius back out. Because the scales have different zero points, an offset (not just a factor) is involved.
