openaq.utils.mass_to_mix¶

openaq.utils.mass_to_mix(value, param, unit='ppb', **kwargs)[source]¶

Convert units from ug/m3 to ppb or ppm. The conversion assumes an ambient pressure of 1 atmosphere and ambient temperature of 25 degC.

Parameters:	value (float) – the concentration in ug/m3 param (string) – the parameter to convert {‘co’, ‘no’, ‘no2’, ‘so2’, ‘o3’} unit (string) – the desired output unit {‘ppb’, ‘ppm’}
Returns:	value
Example:

>>> import openaq
>>> conc_ugm3 = 100
>>> conc_ppb = openaq.utils.mass_to_mix(conc_ugm3, param='co', unit='ppb')
>>> conc_ppb
114.5
