PS = HP ? - school boy
Hi
Can someone tell me if Ps is the same measurement as HP? e.g 110Ps = 110 HP.
And also, whats the difference between HP and BHP? I Know that BHP is more but what dose BRAKE mean, or is it BREAK........?

PS does roughly equal BHP. 1PS = 0.986BHP

I believe its called BHP because it is measured using a Brake Dynometer.

Thank you Tomo, I will find that website very useful.

I know that manufacturers use PS as a measure of power because it give a higher figure than BHP or kW. The prospective buyer thinks that he is getting a higher power when actually it is just a play on figures. PS is a German measure, and literally means Pferd(horse) staerke(strength or force). BHP signifies actual power measured at the engine output shaft by a brake and a rev. counter (as opposed to IHP indicated horse power which is calculated). We have a past thread on this. Perhaps one of the mods can help?

I believe PS(or DIN) is the measure of BHP at the crankshaft with all the essential ancillaries connected to the engine - water pump, alternator etc.

The SAE HP rating was with these items disconnected. This measurement is(was) mainly used in the USA.

There is no simple conversion between DIN & SAE as it depends on the power these ancillaries consume. I recall my first Audi 100 had 100bhp and 112bhp SAE.

And what about RAC horsepower?!

have to confess I still convert to antideluvian mpg for the
sake of being understood.


Not just for that reason. To the best of my knowledge, and for the time being at least, the UK will retain miles and miles per hour for the purposes of road signs.

...but we buy our fuel by the litre, L'escargot.

Wish we could make our mind up if we are using imperial or metric.

And PS stands for pfund sterke , IIRC, which is German for horse power. They are slightly smaller than the British ones as will be seen from the above.

Giving fuel consumption as x litres per 100km is arbitary and awkward, because of the use of 100km.

x miles per gallon is a pure figure and the higher the figure the more economical the car is.

x litres per 100km is an arbitary figure and counter tuitive. You want a car to be more economical so the higher number should be better, but it is not.

I have no opinion on Imperial or Metric, although we should use one or the other and not both for national things like motoring. However, There should still be an allowance for small businesses so that we can continue to use pounds and ounces etc. Otherwise we will play cricket on a 22m pitch (Ugh).

I don't agree. The use of 100km is no more arbitrary than basing the measure on one gallon of fuel. In fact, far from being counter-intuitive, it makes perfect sense. The lower the L/100km figure, the less fuel you're using. It's only because we're not used to thinking in a different scale that it seems a little odd at first. The rest of the non-Amercian world manages it and I don't see why we can't either.

I agree with HJ. The bit that really drives me nuts is that in this country we're so half-hearted about adopting the metric system. I buy fuel in litres, my dumb car displays MPG; the air line at my local filling station displays psi and the handbook for my car quotes bar for tyre pressures. This half-baked sentimentality for 'imperial' measures doesn't help anyone. It's time miles, yards, gallons ounces and the rest of them were dumped once and for all. And that means PS, too, I think. Shouldn't that be Kw?

I prefer MPG only because it's what I'm used to - however I don't see why l/km is any worse. If we measured distance in km then it may start to catch on as we already buy fuel in litres.
Otherwise we will play cricket on a 22m
pitch (Ugh).


BTW, that'll be 20.1m between wickets ;-)

"...but we buy our fuel by the litre,"

It's in the hope that we do not notice the diabolical price of a gallon!

It is a subjective matter. I think the older you are the less you like the changing of those measurements you are comfortable with.

I particularly dislike the imposition of the metric measurements by the EEC.

Bringing it back to motoring - I read somewhere , I think possibly Christopher Booker in the Telegraph saying that a number of towns and cities may have been in breach of the law when setting up the transfer of parking regulations to local authority control and that thousands of parking fines may have to be repaid.

The city that he mentioned in particular was Sunderland - home of the metric martyrs.

Anybody see that article?

Very interesting if you have been fined for parking there.
