Ever stared at a soda can and wondered how its 12 fluid ounces relate to cubic inches? Or maybe you're restoring a classic Mustang and need to translate that 302 cubic inch engine into liters for modern parts? That's where cubic inches to liters conversion becomes your best friend. This guide isn't just about numbers – it's about bridging two measurement worlds that shape everything from your morning coffee to cross-continental engineering projects.
Unit definitions
What is a cubic inch (in³)?
A cubic inch measures volume in three-dimensional space equal to a cube that's 1 inch long on each side. Picture a sugar cube – that's roughly 1 cubic inch.
- Symbol: in³
- Common uses: Engine displacement, small packaging volumes, industrial design
- Definition: 1 inch × 1 inch × 1 inch = 16.3871 milliliters
What is a liter (L)?
The liter is the metric system's volume superstar, used worldwide for liquids and gases. One liter fills a cube that's 10 cm (about 4 inches) on each side – think large water bottle.
- Symbol: L
- Common uses: Beverage containers, fuel efficiency ratings, laboratory measurements
- Definition: 1 cubic decimeter = 1,000 cubic centimeters
Conversion formula
The magic number here is 0.0163871. Multiply cubic inches by this value to get liters:
Liters = Cubic inches × 0.0163871
Need to go the other way? Flip the equation:
Cubic inches = Liters ÷ 0.0163871
Example calculations
- Classic V8 Engine:
Convert 350 cubic inches to liters:
350 × 0.0163871 = 5.735 liters
(That's why you hear "5.7L V8" in muscle car talks) - Water Cooler Jug:
Convert 5 liters to cubic inches:
5 ÷ 0.0163871 ≈ 305.1187 cubic inches

Historical background
The cubic inch has roots in 18th-century British measurement systems, becoming crucial during teh Industrial Revolution for machinery specs. Liters emerged from 1795 France's metric system push, originally defined as 1 cubic decimeter. Fun fact: The liter was briefly demoted in 1901 to a "non-SI unit," but its practicality kept it in global use.
Interesting facts
- Muscle Car Math: A 426 Hemi engine's 426 cubic inches equal 6.98 liters – hence the "7.0L" badge

- Global Mix-Up: The UK uses liters for beer, while US breweries often use cubic feet for tank volumes
- Space Oddity: NASA's Space Shuttle main engine burned 1,100 liters of fuel per second – that's 67,130 cubic inches!
- Medical Precision: Syringes often show both mL (1/1000th of a liter) and cubic inch equivalents
FAQ
It's crucial for understanding engine sizes in international contexts, comparing liquid volumes, or working with mixed measurement systems.
Cubic inches (in³) are imperial/US volume units, while liters (L) are metric. 1 liter equals about 61.0237 cubic inches.
Multiply liters by 61.0237. For example, 2 liters = 2 × 61.0237 = 122.0474 cubic inches.
Absolutely! Many car manufacturers list engine size in liters, while older models or US specs might use cubic inches.
Only when measuring volume. They belong to different measurement systems, so context matters in usage.
