Knowing how to transform CC to HP deserve to be particularly useful because that making calculations. For example, once dealing with small appliances, you’ll require to consider engine size and also power.

Fortunately, converting each is quite basic to help you discover the perfect power tools.

What Is CC?

CC describes cubic centimeters, a measurement used to express engine displacement. It’s in the same league as quarts, pints, and also other units offered to measure volume.

When CC is provided in product descriptions, it tells you the amount of volume the pistons move in a single revolution.

To put it simply, the bigger and stronger one engine is, the greater the CC rating will be due to an ext massive displacement. Horsepower, top top the various other hand, measures an entirely various metric.

Why does Engine Displacement Matter?

You might think that horsepower is all that matters when it comes to picking tools, when, in fact, engine displacement determines the torque and also horsepower the engine produces.

The direct correlation the CC to HP is the the greater the CCs, the much more power the engine will certainly create. A few other factors you have to consider about engine displacement include:

Fuel Consumption

This theory additionally applies to horsepower, as an ext powerful engines consume more fuel. The higher the CC rating of your tools, the more fuel you’ll go with as the air/fuel mixture is greater.

With the said, it’s usual to expect a larger engine will consume an ext fuel because that power.


Larger engines are likewise going to become much more costly end time, especially as castle need much more maintenance.

Not only will they be consuming much more fuel, but they’ll likewise require much more power come run. The more powerful the engine is, the an ext wear and tear it will suffer over time.

Whether it’s her vehicle, a lawn mower, or various other equipment, girlfriend must constantly get consistent maintenance for an effective engines.

What Is HP?

HP is likewise referred to as horsepower and also describes the quantity of job-related that an engine does. You’ll often find that it’s among the many advertised features of small and large engines alike, specifically in vehicles.

Farm devices is an additional industry that frequently relies on speech ratings. You’ll often uncover tractors advertised as having specific drawbar, engine, and PTO speech ratings.

With the said, horsepower offers a general baseline because that the lot of effort an engine puts into its task.

Factors That influence HP

Many other features, such as torque, determine the complete power an engine deserve to provide. Other determinants include:


The heaviness the the tool or vehicle is among the main components that can influence horsepower ratings. The more heavier a vehicle is, the an ext horsepower it will require to make the automobile move.

You can easily see this in activity if you were to look in ~ a car compared to an SUV. Car will have less horsepower due to the fact that their bodies and internal materials are lot lighter.

Hauling and Towing

When you begin shopping for specific vehicles, such together trucks and farm equipment, hauling power is essential.

Not just will you have actually to element in the load of the vehicle, but the weight of what you’re towing, together well. Because that example, if you’ll it is in hauling a trailer, you’ll desire a car with a greater CC come HP rating.


You’ve most likely seen sports cars through exceptionally high horsepower ratings. As the engine will provide more power, it enables smaller vehicles come catapult at exceptional speeds.

Most of the well-known sports dare on the market have speed ratings to consider. These ratings make it much much easier to check out the impact of heightened speech ratings.

One of the simplest ways to identify speed is come look in ~ your preferred vehicle’s 0-60 mph value. The automobile that takes much less time to with 60 mph will have actually a higher HP.

Fuel Consumption

When it involves fuel, you’ll find that it’s much more than horsepower the affects your fuel consumption.

More powerful tools will require an ext fuel to have actually the engine and other components operate efficiently. This is why bigger gas-operated appliances need to be refueled regularly.

If you desire a device with an exceptional fuel economy, it’s ideal to opt for a less powerful engine. Alternatively, battery-powered and electric tools room a good way to prevent expensive fuel altogether.


How to convert CC to HP

You can have a better understanding the HP to CC and vice versa. Fortunately, most assets will carry out both values in their descriptions or packaging.

Because CC and HP measure two various measurements, you cannot make a direct conversion between the two.

However, many manufacturers suggest that 15 cubic centimeters loose correlates come one unit that horsepower. There are additionally some that keep in mind 17 cubic centimeters equate to one unit the horsepower.

To placed these values to use, all you need to do is convert the total number of CCs by 15 or 17 to gain horsepower.

For example:

1800cc engine/15=120 horsepower

1800cc engine/17=105.9 horsepower

It’s important to keep in mind that this formula won’t job-related for every tiny engine you look at. You must always consult the owner’s guide of your generator or tiny tools beforehand.

You’ll have to take the specific kind of tool you’re working through to determine which counter is best.

CC come HP: eye blowers

One example of whereby a timeless CC to HP counter doesn’t work is through snow blowers. The counter differs since a eye blower’s engine requires much more engine displacement to create one horsepower.

If you to be to compare the HP counter of a motorcycle come a snow blower, a eye blower needs much more CCs.

On average, it can take up to 35cc to generate one horsepower in a snow blower. The CC come HP counter formula then alters to 243cc engine/35 = 6.9 horsepower.

It’s crucial you recognize the genuine strength behind her engine to decision which conversion method is best.

CC to Horsepower: Why the conversions Matter

When you’re able to transform CC come HP and HP come CC, it can be less complicated to pick tools. You’ll additionally get a general idea the the power obtainable from a certain engine.
