@rotflmaopmpqxyz Some of it are actually arbitrary. Remember, they're just variables. And it's actually the greek rho (kind of a curvy P) that stands for density, not simply P.

You have saved my life soooo many times, thank you so much for what you do.

Thank you!

So P stands for pressure, and p is also units for momentum AND density? these confuse me. Also Mass and meters confuse me too
