Many harmful or carcinogenic compounds are synthetic organic
compounds that are easily inhaled into the body as they are “volatile”
or easily evaporated at room temperature.
Can you inform me how to convert mg/m
3
to ppm for
formaldehyde?
For formaldehyde,
At 760 mmHg and 20 °C, 1 ppm = 1.249 mg/m3 and 1 mg/m
3
=
0.801 ppm;
At 25 °C, 1 ppm = 1.228 mg/m3 and 1 mg/m
3
= 0.814 ppm.
Conversion factor from mg/m
3
to ppm for TVOC varies with each
specific organic compound since molecular weights of individual
organic compounds are different. Identification of specific organic
compound is needed.
