Engine Size Chart

Most people judge engines not just by their horsepower and torque numbers but also by the engine size. While larger engines are typically more powerful, they burn more fuel. Engine size can be determined by the displacement of the engine.

What Is Engine Displacement?

Engine displacement is the total swept volume of air created by the pistons as they move up and down in each cylinder. Whether you have an engine that is four, six, or eight cylinders, the engine displacement is all measured the same way. Along with the number of cylinders, when calculating engine displacement, you also need to factor in the bore and stroke. Bore is the diameter of each cylinder while stroke is the distance traveled when the piston moves back and forth.

Engine Conversion Chart

While engine displacement in modern society is typically measured in liters, older big block or small block engines mainly used cubic inches to describe the engine size. Converting engine displacement measurements from one unit to another is a pretty simple process. Here's a chart that should help when converting engine sizes.

For example, if you want to know how to convert 6.2L into cubic inches, you would just need to complete some simple math:

6.2L x 61.01 = 378.262

So, 6.2L is roughly equivalent to 378 cubic inches. That wasn’t too hard, was it?
