I was curious, so read up on wikipedia.

somebody measured horses in 2023, and foumd that horses produce 5,7hp https://en.m.wikipedia.org/wiki/Horsepower

edit: wikipedia links to youtube

https://www.sciencefocus.com/science/how-much-horsepower-does-a-horse-have this one also says 15, teorietically 24 🤯

Here is the salient point on the Wikipedia page that explains why horses don’t produce 1 HP:

Watt judged that the horse could pull with a force of 180 pounds-force (800 N)

Basically, Watts made up HP to sell his steam engine to mines and likely made up a number to make the new technology seem better.

Some things never change.

Gotta love autocorrection of Watt into Watts. Watt = J/s = N*m/s = kg*m*m/(s^2*s) = kg*m^2/(s^3)
