That's 13 Watts apparently, in non-American units.

Is there an American unit for power? I thought J/s is universal. 0.017433 Horsepower?

I had expected them to make the title more clickbaity, but that number is about right for a modern lightbulb.

The joke is that Americans like to use metaphors when describing measurements of things, like "as large as a baseball" or "as long as a football field".

However, there are non-SI units that are somewhat commonplace. Horsepower, foot-pounds per second, or BTU per second aren't unheard of.
