That's why I asked about engineering, not driving. Nobody converts torque to power etc.?

The engineers who do that are using metric. Marketing might do this conversion, but they just plug it into a converter and have no reason to know anything more than bigger is better.

Torque to power is just (torque * RPM) / (some constant depending on the units inolved). With ft-lbs and horsepower, that constant is 5252; with N-m and kW, it's 9549. The only thing that changes is the constant.

You make it sound like you'd have to remember a 4-digit constant in either case. That's stupid, it's simply (torque * RPS * 2 * PI).

No, power is just torque times angular velocity. No constants involved.

If you ignore units, sure.
