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
