=== Calculate the numbers ===
Now, make use of the fact that {{tmath|1= \xi\propto\frac{1}{\sqrt{m\mu} } }}. With {{tmath|1= m=23 \,\text{Da},\mu=128\,k_\text{B}\cdot\text{nK} }}, {{tmath|1= \xi=\frac{15.574}{\sqrt{23 \cdot 128} } \,\text{μm}=0.287\,\text{μm} }}.

This method is especially useful for programming and/or making a [[worksheet]], where input quantities are taking multiple different values; For example, with the factor calculated above, it is very easy to see that the healing length of <sup>174</sup>Yb with chemical potential 20.3&nbsp;nK is 
:{{tmath|1= \xi=\frac{15.574}{\sqrt{174\cdot20.3} } \,\text{μm}=0.262\,\text{μm} }}.
