Conversion Factors

[nautigirl]

Can anyone tell me how many PKs and KWs there are in a HP when discussing engine power ratings?

745.7 watts = 1 HP


Hope this helps - but whats a PK?

I think PK is the same as PS, which is horsepower, or very close.

 

[gjeffery]

There is a "metric horsepower"

1 ch = 1 PS = 735.5 watts

I have never used it

Consistency of method and place of measurement will be significant

Thanks for that guys. Just to tidy up, I think ccscott49 is right, PK=PS. A Finnish site uses PK but I notice they talk about Volvo 306PK and Perkins M135PK

Add 1/3 to Kw to get Hp.

Take 3/4 of Hp to get Kw

Andy, thats' the rule of thumb I use ,quick and easy.

1 metric horsepower (CV) = 75 kg * m / sec = 0.7355 kilowatts (kW)
or 1 kW = 1.3596 CV

1 british horsepower (HP) = 550 lb * ft / sec = 0.7457 kilowatts (kW)
or 1 kW = 1.3410 HP

The difference between the two horsepowers is negligeable. The rule of thumb:
“1 kW = 3/4 of 1Hp” is the best for practic use.

I never met the PK. Could it be “Pferd Kraft” in german or something the like in swedish?
Some more sure may surface about it in the thread.

Hope to be of some help.

Sorry!

1 HP = 3/4 of 1 kW, not the reverse as I quoted in my replay by mistake!
