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.
Most engineering in the US is done in metric units. Then marketing applies a metric to imperial conversion.
I suspect China does more engineering in imperial than the US, both in total an per capita: most things I buy made in America are all metric (cars are all metric except for parts designed in the 1960s and the adapter bracket to make them fit on a modern metric car). Most things I buy made in China are imperial. I don't really know for sure, but that is my impression of industry.
