Hi
Does anyone know the formula to convert ppm to mg/m3. I need to know how much 1000ppm NOx into mass? Cheers!

We can show you how to convert it. However, you must furnish real engineering data.

Always define WHAT ppm you are talking about. Is it Parts Per Million of mass or Parts Per Million of volume (or moles)?

There is no such thing as a “Formula”. Do you think that all engineering is about just finding a formula and plugging in the numbers to get an answer? If you want to know how it is done just use the "Search" Forum feature and read all the many past threads on this same subject.

Await your definition of “ppm”.

Thank you for your quick help. Sorry about unclear question. It's is ppmV ( part per million by volume). What do u mean by real engineering data. Does this mean temperature and pressure?
