# Horsepower watch

1. Why are cars still measured in this. Surely is should be something different.
2. Such as?
edit:
On some data sheets, the information is given in kilowatts.

But everyone knows horsepower, and can compare it easily.
3. Like what? window size?
4. Sorry should have made myslef clearer. Horsepower is measued in the power of horses which is perhaps a bit vague.

Surely it should now be measured in a non-imperial way.
5. Sheep-power?
6. O its hard to explain what i mean.

You wouldnt for example measure a boat in whalepower it just seems outdated.

It is. 1 HP = 745.7 watts.
It is. 1 HP = 745.7 watts.
Ahhhh thats what i wanted to know.

Is it normal or is it changing now so that most things are in kilowatts?

The EU's got its fingers in this little pie, so you'll see those energy efficiency stickers on cars, most likely quoting the CO2 emissions and the power output of the engine, measured in kW.

[EDIT] It's also worth noting the difference (albeit small) between mechanical Horsepower and "Metric" Horsepower. Wiki has a pretty good article on it

10. Well you could measure it in pedal power but somehow i dont think it has the same appeal.

Why would you want to change the standard?

Thats like says well I'm bored of miles and kilometers lets make a new measurement that sounds cooler
12. You could say that of anything to be fair. Why is a second as long as it is? Why is a kilo a kilo? It's just a way of expressing a certain amount of something, it's not as if every single horse in the world has one horsepower.
13. You could use ps, its the same as horsepower and it doesn't sound as archaic if thats your issue with it.
14. PS (Pferd Stark, Tcherman for Horse Strength) is actually very slightly less than Horsepower..

Just out of interest, what does that stand for exactly?
16. Look upwards
17. Pferdestärke

No, a unit of horsepower tends to stay right about 745.7 watts. Horses never get stronger or weaker, so why should 'horsepowers'?

He/she/it/frog meant are people switching to kw not does hp variable and change frequently

I know; it was a bad attempt at a lame joke.
