Motorcycle CC to HP Conversion Calculation

12-02-2017Well, that is completely fair, and I have to admit that the question really got me thinking about a ballpark calculation. Keep in mind that ballpark is exactly what you are going to get – a range of CC per HP. Motorcycles come in such a wide variety of shapes, sizes, designs, and uses that the conversion factor can vary kind of widely.

How to Calculate the Mill Rate

A mill rate determines the amount of property tax each homeowner is responsible for paying. This tax amount is expressed as one dollar for every $1,000 of assessed property value; mill or per mill means per thousand. Property taxes are often expressed this way by municipalities, so it can be useful to understand how the mill rate is calculated.
