Wait, is the engine power measured in something else than KW nowadays?
I think that the HP -> KW switch happened something like 20 years ago, at least in my country.
- freeone3000 7y agoEngines in the US continue to be measured in horsepower.
- tigershark 7y agoOk, makes sense then, thanks.
- userbinator 7y agoEven in Europe, where there's even a metric horsepower that's often used in advertising and such: https://en.wikipedia.org/wiki/Horsepower#Metric_horsepower_(PS,_cv,_hk,_pk,_ks,_ch) https://en.wikipedia.org/wiki/Horsepower#Metric_horsepower_(...
- walshemj 7y agoI worked on Audi websites a while back back and Ps was used even on the German sites
- ehnto 7y agoI still see Japan use PS, which is known as Metric Horsepower. I think it comes from the German words for Horse Power, "Pferdestärken". It's 1 PS == 0.98632 HP
- mhh__ 7y agoVehicle dynamics literature does seem (as an outsider) to involve a slightly weird blend of imperial and SI units, research nowadays is metric but old research being cited in textbooks (i.e. RCVD has a lot of imperial)
- gambiting 7y agoAnyone in the world measures engine power in kW? That's odd. What country is that?
- Symbiote 7y agoIt seems standard on car adverts and specifications in the EU, in addition to whatever local unit is preferred. I'm not really interested in cars, so I don't know if there's a European country where power is casually discussed in kilowatts.
- tigershark 7y agoItaly, but also in UK they are measured in KW.
- walshemj 7y agoNot seen that to be honest HP is used - to much risk of the Daily mail kicking off
- martyvis 7y agoIn Australia, car engine power is specified in kilowatts (kW), and torque in Newton-metres (Nm)
- tigershark 7y agoAnd apparently most of the countries use the SI unit instead of the HP. From Wikipedia: Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1, 2010, the use of horsepower in the EU is permitted only as a supplementary unit.
- detaro 7y agoBut do people in those countries use it? At least here in Germany, it's a bit like screen sizes: sure, the manufacturers and sellers have to state the SI unit, but everyone prints the other unit too, and people basically only talk about PS in cars and inches in screens.
