Watt Are We Doing With Our Units?

The eternal struggle of unit confusion in physics! On the left, we have a gang of lightbulbs proudly declaring "We Are 60 Watt Lightbulbs" - measuring their power consumption like proper electrical devices. Meanwhile, the confused cartoon character on the right is having an existential crisis because it measures brightness in lumens instead of watts.

This is peak engineering humor that highlights how we constantly mix up our units. Watts measure power (energy per time), while lumens measure actual light output. A 60W incandescent bulb might produce 800 lumens, but a modern 9W LED can do the same! No wonder the poor lumen-character feels like chopped liver compared to the watt-gang.

The title about kWh vs megajoules just twists the knife deeper into our collective unit-conversion wounds. It's the scientific equivalent of showing up to a metric party wearing imperial units.
