In terms of automobile specifications, 1 horsepower is roughly equivalent to 15 to 17 cubic centimeters. While these two units are both used to describe a vehicle's engine power, cubic centimeters cannot be converted directly to horsepower. Cubic centimeters (cc) and horsepower (hp) are units that belong to different measurement scales; cubic centimeter is a unit of measure of volume, while horsepower is a unit of measurement of power.
Know MoreCar engines, particularly racing cars and dragsters, are labeled according to the magnitude of engine displacement. This figure is the volume driven by all pistons of a reciprocating engine's cylinder in one motion from top dead center to bottom dead center. Engine displacement is usually declared in cubic centimeters or "cc," hence the label attached to car engines.
A car engine generates power from the combustion of fuel. While engine displacement can affect the power generation of a car engine, there are other factors that may come into play. Some of these variables include the cylinder size, number of cylinders, compression ratio, efficient air entry, improved exhaust exit, overall vehicle load and fuel injection.
Vehicles that are highly tuned have the least cc-to-hp ratio. This ratio signifies how well the fuel is swept across the cylinder pistons and converted to power. Most F1 racing cars have top-notch cc-to-hp ratios, while gigantic engines on shipping lines waste too much fuel to propel the ship forward.

Simply multiply the known information by the conversion factor, cancel the units and solve the equation.
Full Answer >You cannot directly convert PSI to GPM. They are two different units of measure. PSI measures pressure, and GPM measures flow rate. However, if other variables are known, you can use Bernoulli's equation to indirectly make a conversion. The following assumes the flow is in a pipe and the pipe diameter is known. It also assumes a steady state incompressible flow.
Full Answer >Since there are 15 to 17cc to every 1 horsepower, a 49cc engine typically has about 3 horsepower. However, this conversion may be offset by certain features, like supercharging and exhaust turbo boosting.
Full Answer >The horsepower of a 250cc engine varies greatly, depending on a number of factors. The average horsepower for a 250cc in a dirt bike is between 20 and 30. A Briggs & Stratton snow blower using the same style of engine has only 8.5 horsepower.
