Temperature units in practice
Weather, ovens and industrial processes in Pakistan use Celsius, while many medical thermometers and imported appliances use Fahrenheit. Kelvin is the scale of science and engineering, starting at absolute zero.
Temperature scales have different zero points, so converting is not a simple multiplication. The converter adds or subtracts the offset as well as scaling the size of the degree.
