<![CDATA[Scale for PM 2.5 not correct]]>The PM 2.5 scale is not correct. The range is not standard. How does this number as shown by the flag relate to the standard 0-500 scale?

I would like to sent a screen shot, how can I send it?

Can you provide a formula to convert the Windy number to the 0-500 scale. I fully understand it is not a simple linear relationship. I can do the math given that the other variables are provided in the data types you present.
Thank you.

The AQI index is calculated with other pollutants as well as PM 2.5. The scale for PM 2.5 is in micrograms per meter cubed and is one factor used to calculate the AQI.

This bug has already been reported.
It is really important to have this scale conform to global standards
Are you going to fix this?
