Convert bVOC ppm to mg/m3

[josemartinez]

Hi,

I don't know if it is already answered in other thread but I have a project where I'm using a BME668 to read ambiental data and this sensor returns bVOC in ppm. Is there any posibility to get this in mg/m3 or any easy way to convert it?

Thanks.

Hi josemartinez,

In principle, the gas concentration units of ppm and mg/m3 cannot be directly converted. Because VOC is a comprehensive substance and not a single gas component, if conversion is required, it needs to refer to a specific substance and conduct specific conversion according to its specific molecular weight.
