Farting is an essential day to day activity. It helps maintain a healthy lifestyle and keeps bloating away. There are multiple types of farts, but the most common way to categorize them is by the loudness/stinkyness ratio. Essentially, the louder the fart, the less stinky (fully silent farts are the most nocive for surrounding victims). Farting can be enjoyed alone or can be turned into a group activity.
The rankness of a fart can be expressed in decibel-Farts (dBF), a logarithmic scale where dBF = 10 log10(F1/F2).
Characterizing F in standard units is a bit of a chore, but broadly speaking the resolution concentration of hydrogen sulfide (H2S) in air for humans-- the concentration at which 50% of people can detect its odor-- is about 4.73ppb, or 4.73 x 10^-9.
Air at sea level (1atm or 760mmHg) at 15°C contains about 2.53 x 10^25 molecules of mixed gasses, so the resolution volume of a H2S in humans is about 1.19 x 10^17 H2S molecules per cubic meter at 1atm at.15°C. This is value is your F2.
A typical human fart has a concentration of anywhere between .001ppm and 1ppm of H2S concentration, or between 1x10^-6 and 1x10^-3, thus between 2.53x10^19 and 2.53x10^22 H2S molecules.
Therefore the rankness of a typical fart could be expressed as falling somewhere between -60dBF and -30dBF.
This is a useful expression of rankness for modeling attenuation over time, accounting for dispersion, wind drift, and distance from the zero point.

Only flatulence novices believe all Deadlies must be Silent.
Truly, the quality of the stink factor is congruent to the proximity of the fecal matter to the anus.

But what if the quality and composition of the fecale matter is shittier than shit? Then the fart quality would be compromised

The “fecale” spelling is way funnier than it has any right to be.
