The relationship between cubic centimetres (cc) and horsepower (hp) is complex and depends on many factors. First of all, it's important to note that cc is a measure of engine size, while hp is a measure of how much power it produces. Generally, a larger engine will produce more power, but the ratio isn't uniform across all engines. It depends on how well-tuned the engine is, as well as the type of fuel it uses. Most modern passenger cars, however, do fall into a small range of ratios.

Instructions

1. 1

Divide the cc of the engine by 15. For example, the 1800cc of a 1.8-litre 16V Ford Escort's engine divided by 15 yields 120hp.

2. 2

Divide the cc of the engine by 17. For example, the Escort's 1800cc divided by 17 yields approximately 106.

3. 3

Recognise the horsepower falls somewhere in the range established by the previous steps. In fact, the Escort's horsepower is 115. Its cc to hp ratio is 15.6522.
