Q:

# How do you convert CC to horsepower?

A:

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.

Car 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.

• A:

There are approximately 15 to 17 cc per horsepower, so 600 cc is equal to 35 to 40 horsepower. There are too many variables to enable an exact conversion, so the number of horsepower to 600 cc can only be estimated.

Engine displacement, measured in cubic centimeters ("cc"), and power, measured in watts or horsepower, are separate measurements that cannot be precisely compared to one another. However, several examples of modern 1235cc engines show horsepower ratings between 135 and 165.

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.
