“Power” (or “Potenz” or “puissance”) is the most common claim, but potential, pondus, and percent are also common. When the original author designated it, he implied that it was just a random mathematical letter, akin to x, and that it didn’t stand for anything, although from context one could argue it stood for potential?
I mean that’s like the guy who invented the Jraphics Interchange Format. He may have invented the idea, but everywhere I look, even on the most reputable of sources, it’s “Ghiff”/“potential”
