- Total mass / number of particles released = mass per particle
- Particle mass contributing to a grid cell is summed over the "sampling" period
- A particle is a computational particle, it may represent a gas or particle
- One computational particle represents many billions of pollutant molecules (Avogadro's # 6x1023)
- Mass of input units = output units: for example g/h to g/m3
- Units only matter when doing mass to volume conversions
