| contents | This brief note presents standard computations of primordial black hole mass $M$ given perturbations of scale $k$, and their late-time abundance $Ω_\text{PBH}$ given their initial density fraction $β$. I recap the assumptions made in these computations and present formulas and reference charts useful for a working cosmologist. |
