cubic inch to liter – How to convert in³ to L
The conversion from cubic inches to liters bridges the imperial and metric systems. Cubic inches remain common in the United States, while liters are widely used around the world for beverages, appliances, and fuel. Being able to move between them is practical for global trade, product design, and daily life.
What is a cubic inch (in³)?
A cubic inch is the volume of a cube with sides of 1 inch. It equals about 16.387 cm³ or 0.016387 L. In the US, it is still used in engine specifications, product design, and some older technical manuals.
What is a liter (L)?
A liter is a metric unit equal to 1000 cm³ or 1 dm³. It is the standard measure for beverages, packaging, medical solutions, and automotive fluids worldwide.
Conversion formula – cubic inch to liter
The relationship is fixed and straightforward.
The base equivalence is:1 in³ = 0.016387 L
To convert cubic inches to liters:1 cubic inch = liter × 0.016387
To convert liters to cubic inches:1 liter = cubic inch × 61.024
Examples:
-
200 in³ ≈ 3.28 L -
10 L ≈ 610.24 in³

Do you know?
-
In appliances: Refrigerator capacity is often listed in cubic feet for US buyers, but in liters for global catalogs. Since 1 ft³ equals 1728 in³, conversions often start from cubic inches.
-
In automotive history: Classic US cars described engines in cubic inches, while modern spec sheets translate them into liters (e.g., 350 in³ ≈ 5.7 L).
-
In beverages: International drink packaging almost always uses liters, while older American manuals sometimes include cubic inch equivalents for volume.
What connects V8s and water bottles
A good example of this conversion appears in the automotive world. An American engine once advertised at 302 in³ is today more commonly known as about 5.0 L. This translation makes it easier for international buyers to compare engines across markets.
The same principle applies in households. A storage container sold in the US may be listed at 400 in³, while in European catalogs the same item is labeled 6.55 L. The conversion makes sure the product is understood no matter where it is sold.
Two systems, one shared measure
The formula 1 in³ = 0.016387 L shows how a single unit connects two measurement traditions. Whether you’re shopping for a car, comparing kitchen appliances, or exporting goods, the ability to convert between cubic inches and liters ensures clarity.
It’s not just a calculation — it’s a way of making sure products, designs, and ideas cross borders smoothly.
