CC to HP Calculator

Quickly calculate the estimated horsepower (HP) by simply entering the cubic centimeters (CC). This CC to HP calculator will perform both forward and reverse conversions. You can convert HP to CC or vice versa.

What is CC in Engine?

CC (cubic centimeters) refers to the size of an engine. It is a measure of the space the pistons occupy in the cylinders as they move up and down, releasing and later pulling in the air and fuel. The greater the CC, the larger the volume of the mixture the engine can combust and the more power it produces.

The CC to HP Formula

There is no specific formula for converting CC (engine size) to horsepower (HP), as there are multiple factors that affect power output, such as design, fuel, and speed (RPM). However, there is a basic approximation that can be used for most normal engines, which is:

HP = CC ÷ 15

For the reverse calculation, the formula is:

CC = HP × 15

How to Convert CC to Horsepower (Step-by-Step)

Let us show how to do the CC to HP conversions and vice versa through practical examples.

Example 1: Convert CC into Horsepower

Let's suppose that there is a motorcycle that has a 600 cc engine. How do you figure out the estimated horsepower?

Determine the engine displacement in total: 600 CC.

Now we can use the formula 

HP = CC ÷ 15

Put in the values:

HP = 600 ÷ 15

HP = 40

This means that the horsepower is 40.

Example 2: HP to CC Conversion

Let us now suppose that you are interested in a commercial generator that has a horsepower output of 20. In this case, we have to figure out how big the engine is.

Here, the horsepower is 20 HP.

We can now use the reverse formula: 

CC = HP × 15

Put in the values:

CC = 20 × 15

CC = 300

This means that the engine size is 300.
