How to covert CC to horsepower

Im having trouble finding a site that can convert CC into horsepower. I was wondering if you knew how to change 246 cc into h/p somehow.

About the only way would be to take it to a shop and have it put on a machine to measure it.

Horsepower depends on much more than just engine size. For example, a well tuned up 246 cc engine will have more horsepower then an old one. There are too many other factors for converting directly.

If it is a new engine then I am sure you can find data sheets for it someplace, such as the dealers website. You are sure to find both engine size and horsepower listed there.

Do you what the "CC's" [as in a 250 cc motorcycle engine] are for a 15 horsepower Briggs and Stratton engine?

Or cubic inches [as chevy 350 cubic inch engine] would be in CC's [as in 500 cc Yamaha]? Please.

Thanks

The symbol cc stands for cubic centimeter, while the symbol ci stands for cubic inches.

Both are units of volume and you can convert between them on the Volume conversion page. Another common unit of volume for engine size is the liter.

You cant directly convert volume to horsepower. But in your case, you have a 15 horsepower Briggs and Stratton engine, you'll just need to know the year it was made, then contact the Briggs and Stratton company and they will be able to tell you. Possibly a dealer could help too, maybe even their website will have that information.

i would like to convert 988cc in to horse power

O that is as easy as pie all of you people are wrong you certanly can convert cc in to horse power just by taking the first numer and taking 1 away so for instance 988 cc would be 98 horse powere easy as that. I am seventy four and I know my stuff. But if it was 49 cc you would take two away and take away the 9 for good so it would be 2 horse power.

I'm not sure that would be very accurate. A cheap 100 cc engine would certainly have lower horsepower than a brand new high performance 100 cc engine.

Though no doubt there are rules of thumb that are accurate enough for most purposes.

"old man" i still dont quite understand if a car (skyline) had 3500cc what would it be in hourse power?

Roughly 250 HP on 3500 CC Skyline. Alot of factors can make that number different though. But it's a rough estimate if that is what you want.

Roughly 250 HP on 3500 CC Skyline. Alot of factors can make that number different though. Like where the torque is....Shaft or Rear Wheel, and it can also depend on the tune....it can go up or down drastically. Ford Mustangs are roughly 193 HP at around 3800cc's.

But again, it's a rough estimate if that is what you want.
