Yeast output will be calculated by taking a sample of the fermentation broth when the fermentation has ended, and determining the (dry) yeast content per volume of the broth. This then needs to be multiplied with the final volume of broth in the fermenter when the fermentation ended, to obtain the total amount of yeast.

```tex
m_{\text{yeast}} \;=\; 
\left( \frac{m_{\text{sample,dry}}}{V_{\text{sample}}} \right) \cdot V_{\text{final}}
```

The fermenter yield is a measure of how efficiently the carbon source (molasses, typically) has been "converted" to yeast biomass. This will be calculated by dividing the yeast output by the fed molasses, on dry weight basis.

```tex
Y_{\text{fermenter}} \;=\; 
\frac{m_{\text{yeast}}}{m_{\text{molasses}}}
```
