The H2S content in my device is 30 ul/l. What is the value in mg/m3 when converted to SO2? Thank you, points appreciated

In my setup, the H2S concentration is 30 ul/l; if the gas already contains oxygen, then no air is needed for dilution during oxidation, and the sulfur dioxide concentration after oxidation will still be 30 ul/l. Using the formula 30*64/22.4, we get 86 mg/Nm3. With such a low concentration, the change in volume before and after the reaction can be ignored. If there is air dilution, it depends on how much air is added.
