Conversion Formula
The formula to convert cubic inches (ci) to liters (L) is:
Liters = Cubic Inches × 0.0163871
This works because 1 cubic inch is exactly 0.0163871 liters, so you multiply the number of cubic inches by this constant to get liters. The factor comes from the definition of the units and metric conversions.
Example calculation for 408 ci:
- Take the volume in cubic inches: 408 ci
- Multiply by the conversion factor: 408 × 0.0163871
- Calculate the product: 6.6873168 liters
- Rounded result: approximately 6.6873 liters
Conversion Example
Let’s convert 250 ci to liters step-by-step:
- Start with 250 cubic inches
- Multiply 250 by 0.0163871 to convert to liters
- 250 × 0.0163871 = 4.096775 liters
- Result: 250 ci equals about 4.0968 liters
Another example, converting 500 ci:
- 500 × 0.0163871 = 8.19355 liters
- This means 500 cubic inches is roughly 8.1936 liters
One more, converting 100 ci:
- 100 × 0.0163871 = 1.63871 liters
- So, 100 ci equals about 1.6387 liters

Conversion Definitions
ci (cubic inch): A cubic inch measures volume in the imperial system, defined as the space contained within a cube that measures one inch on each side. It is commonly used in the United States for engine displacements and small volume measurements, representing a compact unit of volume.
liters (L): A liter is a metric unit of volume equal to one cubic decimeter (10 cm × 10 cm × 10 cm). It measures liquids and gases and is widely used around the world in science, medicine, and everyday life. One liter equals 1000 cubic centimeters or approximately 61.024 cubic inches.
Conversion FAQs
Why is 1 cubic inch equal to 0.0163871 liters?
The conversion factor comes from the metric definition of a liter and the imperial measurement of an inch. Since 1 inch equals 2.54 centimeters, a cubic inch equals (2.54 cm)^3 = 16.3871 cubic centimeters. Because 1 liter equals 1000 cubic centimeters, dividing 16.3871 by 1000 gives 0.0163871 liters per cubic inch.
Can I convert cubic inches to liters without a calculator?
You can estimate by remembering that 1 ci is about 0.0164 liters. For rough conversions, multiply cubic inches by 0.0164, then round as needed. For precise work, a calculator or conversion tool is recommended to avoid rounding errors.
Are liters larger than cubic inches?
Yes, a liter is larger than a cubic inch. Since 1 cubic inch is 0.0163871 liters, it takes about 61.024 cubic inches to make one liter. So liters measure bigger volumes compared to cubic inches.
Does temperature affect ci to liters conversion?
The conversion factor itself doesn’t change with temperature because it relates fixed units of volume. However, actual physical volumes of liquids or gases can vary with temperature due to expansion or contraction, but the unit conversion remains constant.
Is this conversion used in engine measurements?
Yes, engine displacement is often measured in cubic inches in the US, but engine sizes are also expressed in liters internationally. Converting ci to liters helps compare engines using different measurement systems.
