Engine Size ChartLast Updated August 4, 2019 | Alison Smith
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 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.
|Original Unit||Desired Unit||Multiplier|
|Cubic inches||Cubic centimeters||16.39|
|Cubic centimeters||Cubic inches||0.06101|
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?

Before liters became the typical unit for measuring engine displacement, cubic inches was the standard way of determining engine size. Rather than doing the math yourself, check out this handy engine conversion chart that will tell you the cubic inches, cubic centimeters, and liters of popular engine sizes. If you don’t see your size listed, check out the simple conversion table to calculate your engine displacement!

If you know anything about diesel engines, then you’ve probably heard the names Cummins, Power Stroke, and Duramax at some point. While Ram trucks are known for the Cummins engine, Ford’s diesel equivalent is the Power Stroke while Chevy has the Duramax. But what are the similarities and differences between the Cummins vs Powerstroke vs Duramax? Check out how these three diesel engines have evolved over the years.
Most people have a clear preference when it comes to diesel vs gas, but what are the advantages of diesel engines? Why might someone want to opt for a diesel engine rather than the more traditional gasoline motor? There are many benefits of diesel, however, there are always negatives to offset the positives. Although diesel is more efficient and can provide more torque, diesel cars or trucks can be more expensive to buy as well as to refill at the gas station.
