CC To HP Calculator | Approximation, Range & Average

Source: rurallivingtoday.com

Common terms like “cubic centimeter” (cc) and “horsepower” (hp) are often used to describe engines. Even though these two terms are not exactly the same, they give you an idea of the size and power of the engine. The standard HP, or horsepower, is what most Americans are used to. 

By figuring out the CC/HP, you’ll know more about the specs of your car, motorcycle, speedboat, and ATV. This is important if you want to buy any of these vehicles.

CC to HP/ HP to CC Calculator/Convertor

If you can’t think in CC but still need to figure out how much power your engine needs, you can convert the CC rating using this calculator.

What is cc?

CC is a unit of volume that is also called engine capacity or displacement. It measures the total amount of fuel or air that the pistons of an engine move. It seems that low-powered engines can move about 1,000 to 2,000 cubic centimeters of power, while high-powered ones can move about 7,500 to 8,200 cubic centimeters of power.

Some of you might be more familiar with liters because that’s how some car companies measure engine size. With this in mind, you can also convert liters to cc by multiplying them by 1000cc or cc to liters by multiplying them by 0.001 or dividing them by 1000.

How To Calculate cc?

To figure out how big your car’s engine is, you can use the given formula. Usually, you can find the bore diameter, stroke length, and the number of cylinders of an automobile engine in the user’s manual or on the manufacturer’s website.

Formula:

V = π/4 x (D)² x H x N

Where:

V: Cylinder Volume or cc

π: 3.142

D: Bore’s Diameter

H: Stroke’s Length

N: Number of Cylinders

CC is important to calculate since it is directly related to your engine’s performance. Following are a few things that are related to the engine’s cc.

Power

The size or capacity of your engine affects how much torque and horsepower it has. Most of the time, a high-capacity engine will pull more air into its cylinders, which will increase the amount of air in the engine. This increases the amount of gas in your car’s engine. So, it would need more power to burn the fuel already there.

So, the engine’s power output is directly related to how much it can hold. When the engine has a lot of power, it means that it has a lot of capacity.

Fuel Efficiency and Mileage

An increase in fuel consumption accompanies an increase in power output. On the other hand, when this happens, fuel mileage goes down. This means that the engine’s cc has the opposite effect on fuel mileage and efficiency.

What is HP

HP means “horses per hour.” It is a measure of power or, to use the technical term, “the rate at which work is done.” It is an imperial unit. 1 horsepower is equal to 750 Watts or 550 foot-pounds per second. It’s found by multiplying force (in pounds) by distance (in feet) and dividing the result by time (minutes).

Horsepower comes from the watt, which is one of the main units of measurement for power. Because it can be hard to tell the difference between imperial horsepower and the metric horsepower, it is also used to measure the power of internal combustion engines.

How To Calculate HP?

The following formula must be used to figure out horsepower:

Formula:

Horsepower = (T x RPM) / 5,252

Where:

T: Torque

RPM: Speed

The horsepower of your engine is very important because it affects the other specs of the engine, which are as follows:

Speed

From the above formula, you can see that horsepower and speed are related in a direct way. That means that the faster a car is, the more horsepower it has. Whether you need a slow or fast mode of transportation depends on your needs and how you live.

Torque

Both torque and horsepower have to do with how powerful an engine or car is, so a vehicle with a higher horsepower rating can haul things better than one with a lower horsepower rating. This is also why cars with a lot of weight tend to have a lot of horsepower.

So, if you want to pull a trailer, hitch mount cargo carrier, or other gear for your adventures, you should look for one with a high horsepower rating.

Gas mileage and fuel efficiency

If the engine wanted to make more horsepower, it would need to put more fuel into the cylinder. That means that a higher HP rating will hurt the engine’s gas mileage and fuel economy, which is similar to engine capacity.

How is CC Converted to HP?

Calculating Range

Several pictures that show the slight relationship between horsepower (HP) and cubic centimeters (CC) of different engine sizes and types show that one HP is about the same as 14cc to 17cc. For this method of conversion, you can use these numbers.

1. Divide the size of your engine by 14.

2. Divide the size of your engine by 17.

The range of horsepower your car engine has is what you get as a result. The result of step 1 is about the maximum HP, and the result of step 2 is about the minimum HP.

Example: How Much HP is 2000 cc?

1. 2000cc/14 = 142.85HP

2. 2000cc/17 = 117.64HP

Hence, a 2000cc engine has an approximate HP range of 117.64 to 142.85.

Approximation

This method for converting horsepower to cubic centimeters only works for small engines with four cycles. Experts say that a four-cycle engine of about 32.2cc can make one horsepower. This gives us the formula:

HP = Engine size / 32.2

How much horsepower is 200 cc?

200cc/32.2 = 6.21HP

So, a 200cc, small four-cycle engine has about 6.21 horsepower.

Obviously, this is all going to depend on your intended purposes for the vehicle. Almost never in normal life do you need to go from 0 to 60 mph in 4 seconds. The emissions from larger engines tend to be more harmful to the environment. When it comes to taxes, smaller engines are much more wallet-friendly in places like Europe and the United Kingdom, where they are based on the size of the vehicle’s engine.

Naturally Aspirated Engines

There are between 14 and 34 cubic centimeters per horsepower produced by a naturally aspirated engine, which translates to an output of 25 to 70 horsepower per liter. In contrast to forced induction engines, which use turbochargers or superchargers, naturally aspirated engines rely on air pressure alone.

This means that air is being drawn in through the intake manifold and is being meshed with the appropriate quantity of fuel in a seamless fashion. Gasoline and diesel are both acceptable fuels for naturally aspirated engines. Some high-performance vehicles have an impressive power output of over 100 hp per liter.

Turbocharged Engines

With a turbocharger, the ratio of engine displacement to power output can be made to reach incredible heights. The Nissan Skyline GTR R32 is a popular example due to the fact that its 2568 cc engine can be modified to produce 1000 horsepower.

Simple and brilliant, a turbocharger uses high-pressure exhaust gases to spin a turbine, which in turn forces more air into the engine’s combustion chamber. Forced induction refers to the process by which a turbocharger actively pushes air into the engine in addition to the natural air resistance created by the moving vehicle.

Supercharged Engines

One additional type of forced induction system is a supercharger. The power for the supercharger comes from the crankshaft, as opposed to the exhaust gases that are used by the turbocharger to compress the air.

This indicates that the power generated by the supercharger increases in a linear fashion in proportion to the speed at which the engine is moving, just like a naturally aspirated engine would. The addition of a supercharger to an engine can boost its output by up to 40% and even further if the tuning is done correctly.

Factors that Affect the cc/HP Ratio

The cc/HP ratio of an engine is influenced by a wide variety of factors. The most important ones are listed below.

Engine stroke

The kind of engine being used is among the most crucial considerations. Because of the way they are constructed, two-stroke engines typically have a higher cc/HP ratio than four-stroke engines do.

Dimensions of the cylinders

Another important aspect to consider is the number of cylinders as well as their dimensions. As a general rule, the number of cylinders an engine has directly correlates to the amount of power it is capable of producing.

Cooling system

Because liquid-cooled engines are more efficient than their air-cooled counterparts, they are able to produce the same amount of horsepower despite having a larger displacement.

Aspiration

A significant impact on performance is also provided by the aspiration of the engine. Naturally aspirated engines produce the least amount of pollution, but supercharged and turbocharged engines produce significantly more power per unit of fuel burned, as mentioned above.

Materials, tolerances, and compression ratio

There are also a great number of other important factors that have a significant impact on the horsepower per cubic centimeter ratio, such as engine materials, design, tolerances, and compression ratio.

FAQs

Is hp the same thing as cc?

No, the two units of measurement are not the same at all. Horsepower is a measure of how much power something has, while the cubic centimeter is a measure of how much space something takes up.

How many cc is an engine with 3.0 hp?

The size of a 3.0 horsepower engine is about 45 cc. This is not a perfect conversion because cc measures how much space an engine takes up, while horsepower measures how much power it has.

How much horsepower does an engine with 1500 cc have?

About 15 horsepower comes from a 1500 cc engine. This is not a perfect conversion because cc measures how much space an engine takes up, while horsepower measures how much power it has.

How many cc is an engine with 5 horsepower?

The size of a 5-horsepower engine is about 75 cc. This is not a perfect conversion because cc measures how much space an engine takes up, while horsepower measures how much power it has.

How many cc is 1 HP?

Several examples that show the slight relationship between horsepower (HP) and cubic centimeters (cc) of different engine sizes and types show that one HP is equal to about 14cc to 17cc. For this method of converting, you can use these numbers.

Conclusion

The performance of an engine is affected by many things, such as its capacity or displacement and horsepower. These two things are measured in different units, but they are related because they affect the engine’s total power, how well it uses fuel, and how far it goes.

The methods or formulas for converting given above will give you a rough idea. When you start converting, make sure you use the right formula for your unit’s engine. Or you can simply use the calculator provided in his article.
