# scipy.constants.convert_temperature

scipy.constants.convert_temperature(val, old_scale, new_scale)

  Convert from a temperature scale to another one among Celsius, Kelvin, Fahrenheit, and Rankine scales.

  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.

  Notes

  New in version 0.18.0.

  Examples

      >>> from scipy.constants import convert_temperature
      >>> convert_temperature(np.array([-40, 40]), 'Celsius', 'Kelvin')
      array([ 233.15,  313.15])
