Parameters ---------- val : array_like Value(s) of the temperature(s) to be converted expressed in the original scale. old_scale : str Specifies as a string the original scale from which the temperature value(s) will be converted. Supported scales are Celsius ('Celsius', 'celsius', 'C' or 'c'), Kelvin ('Kelvin', 'kelvin', 'K', 'k'), Fahrenheit ('Fahrenheit', 'fahrenheit', 'F' or 'f'), and Rankine ('Rankine', 'rankine', 'R', 'r'). new_scale : str Specifies as a string the new scale to which the temperature value(s) will be converted. Supported scales are Celsius ('Celsius', 'celsius', 'C' or 'c'), Kelvin ('Kelvin', 'kelvin', 'K', 'k'), Fahrenheit ('Fahrenheit', 'fahrenheit', 'F' or 'f'), and Rankine ('Rankine', 'rankine', 'R', 'r'). Returns ------- res : float or array of floats Value(s) of the converted temperature(s) expressed in the new scale.
