I think we all do, but it is not technically correct. We all know what we're referring to tho'.

Horsepower is a unit of power, and is never stated in terms of ft-lb or lb-ft (which are units of torque).
The amount of power is expressed as so many "horsepower", or "hp", or some other unit of power (watt, Btu/hour, etc).

I just added two torque wrenches to my tool sets.

I bought a 3/8 drive that goes to 100 ft lbs and a 1/2 drive that goes to 250 ft lbs.

I shopped some and was willing to settle for solid performance without going to the high end unnecessarily. I ended up with Kobalt. I got mine from Lowes you may find them cheaper on Ebay, etc. They come with a lifetime guarantee.

The 1/2 drive was about $80; the 3/8 was about $60 but I don't recall exactly.

I've used both now checking the antisway bars on the Ford chassis and other applications, and they work just fine.

If you need one over 150# rent one for 1 time install. Buy a cheap 150# one to keep in your T/V for flat tire use on your T/V and towed R/V. Also include a short ext and sockets to fit T/V and towed unit,it makes removal of wheel nuts easier than the tire irons that come with the units. This is for trailers,if you have a (A,B,C,D,or some 5th wheels) you will need a Bigger torque wrench! Youroo!!

Right. "foot-lbs per second" is a unit of power.
But in your previous post, you said only ft-lb (or lb-ft, I forget).
This explains why you can calculate hp by dividing torque by rpm (then multiplying by some constant, 5252, IIRC).

ft-lbs is torque
ft-lbs/sec is power
hp is also power
