What is Horsepower?

Yes those horses can pull. I was picking up a load of logs a little over 2 cords from a Amish man on my trailer behind my 4 wheel drive Chevy and got stuck in the mud. They couldn't drive my skid loader but yanked me out with 2 horses. Steve

KW method i think is way better than HP ratings IMHO

Yes, no doubt about that!

Yes, no doubt about that!

Again.. playing devils advocate.. "no dobut about that!" sounds pretty certain.

So what.. from a scientific perspective makes kW better than HP or than kpm/s or better than Btu/h or better than anything else..

It is .. or appears to be .. a personal preference.. unless you can tell me what makes it better ..
