Different conversion methods for each unit
Length and weight use the scale of the standard unit. Temperature has different reference points, so when converting from Celsius to Fahrenheit, C×9÷5+32 is used. From Fahrenheit to Celsius is (F−32)×5÷9, and from Celsius to Kelvin is C+273.15. Temperatures lower than absolute zero will result in an error.
