Hi Sir/Madam,
I have a project is using the BME680 to detect the VOC value. BME680 which can output the bVOC value in ppm. Is it possible can convert this value from ppm to mg/m3? Also, is it bVOC is same as TVOC?
Looking forward anyone can reply. Thanks a lot.

BVOC is same as TVOC, when BME680 is used to measure indoor air qualilty, it is BVOC; when BME680 is used to measure outdoor air qualilty, it can be said TVOC.
BME680 can output the bVOC value in ppm. But it is not recommended to convert this value from ppm to mg/m3, because this value only estimates breath-VOC concertration to indicate current VOC level (derived form bVOC lab test) no accuracy specified
am a bit confused at that point if we go with bvoc value from BME680, then is it helpful and consider a good effort.
