ELI5: Why are there multiple methods for measuring electricity? (Volts, amps, watts, etc.)

They mean different things.  Instead of electrons, imagine you're measuring a water pipe.

How wide is it?  That's resistance.

How much pressure is inside?  That's voltage.

How fast is the water flowing?  That's amperage.

The water is turning a waterwheel as it passes, how much energy is that using?  That's wattage.
