The amount of horsepower output by an engine depends on more than just the engine size. For example, a tricked out 4.7 liter engine will have more horsepower than an old stock 4.7 liter engine.
You wont be able to convert directly between them. For new cars you may be able to find data sheets that lists both engine size and horsepower. Otherwise you would have to take it to a shop to be placed on a machine to measure it.
This question really has no answer. Displacement (liters) and horsepower are two completely different types of measurements. Displacement measures how big the engine is, and horsepower measures the power output. A bigger or smaller engine doesnt mean more or less power.
To convert engine displacement from liters to horsepower, you can't use a direct conversion, as horsepower is a measure of power output, while liters measure engine size. However, a rough estimate is that a typical gasoline engine produces about 30 to 40 horsepower per liter. Therefore, a 3.5-liter engine might produce approximately 105 to 140 horsepower, depending on various factors like engine design, fuel type, and tuning.
There isn't a direct correspondence between horsepower and displacement. It'll depend on the fuel type, thermal efficiency of the engine, programming (in electronically controlled engines), and other factors.
Liter is a measure of volume; horsepower a unit of power (energy per time unit). You can't convert this directly. If you mean, a motor has so-and-so many liters, in general, more liters means more power - but the volume of the pistons is not the only factor that affects the power.

You don't? The efficiency of all engines varies greatly. You'll have to look up the published specifications for the engine in question, or better yet have the actual engine put on a dynomometer.
horsepower is engine power. cubic centimetres is engine displacement. (sometimes proportional but) they are not directly related.
One cubic inch equals 0.016387064 liters, so a 305 cubic inch engine would convert to 4.998054541 liters, which would be referred to as a 5.0 liter engine.
There is no direct relationship between the cylinder capacity of an engine and the horsepower that it can generate. It depends on the engine design, the fuel amongst other factors.
if the engine is 2.5 liters then I believe it has 165 hp
An engines cubic capacity cannot be converted, mathematically, to horsepower without a host of other information..
To convert cubic centimeters (cc) to horsepower, a general rule of thumb is that 1 horsepower is approximately equivalent to 15 cc in a gasoline engine. Therefore, to estimate the horsepower for a 342cc engine, you can divide 342 by 15, resulting in about 22.8 horsepower. Keep in mind that this is a rough estimate, as actual horsepower can vary based on engine design and efficiency.
