About this calculator
The Temperature Converter converts a temperature value between Celsius, Fahrenheit and Kelvin scales, correctly handling each scale's different zero-point offset rather than a simple multiplicative conversion.
Frequently Asked Questions
Multiply the Celsius value by 9/5 and add 32. For example, 25°C converts to 77°F - the calculator applies this formula automatically.
Unlike length or weight, temperature scales have different zero points, so conversions require adding or subtracting an offset in addition to scaling.
0 Kelvin equals -273.15°C and -459.67°F - the theoretical point at which all thermal motion stops.
