scipy.constants.convert_temperature#

scipy.constants.convert_temperature(val, old_scale, new_scale)[source]#

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

Parameters

valarray_like: Value(s) of the temperature(s) to be converted expressed in the original scale.
old_scalestr: 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_scalestr: 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

resfloat 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
