{**MANY USEFUL CALC LINKS!} ********* Diffusion flux [kg/m2s] tells how fast a substanse solved in another substance flows due to concentration gradients. Diffusion constants [m2/s] are given for several gases in water

*********The efficiency of a ventilation system may be related to temperature and/or pollution concentrations

{Note: This tool is very unspecific to environmental conditions, and cannot enable accurate dosing without significant additional calculations} Use the calculator below to determine the quantity of chlorine dioxide needed for an area in air

{Concentrations of gases in air}

This PPM to mg/m3 conversion is based on the molecular weight of the chemical and it is different for every chemical.

Formulas for calculating ppm & mg/m3, and sampling methods.

***Concentration (mg/m3) = 0.0409 x concentration (ppm) x molecular weight
