Cubic Inches to Liters Converter
Convert cubic inches (in³) to liters (L)
Cubic Inch
Definition: The cubic inch (symbol: in³ or cu in) is a unit of volume used primarily in the United States. One cubic inch equals the volume of a cube with sides of 1 inch each. It equals exactly 16.387064 milliliters or 0.016387064 liters. The cubic inch is widely used for measuring engine displacement in automotive applications.
History/origin: The cubic inch derives from the inch, which has been a standard unit of length in English-speaking countries for centuries. The cubic inch became particularly important in automotive engineering for measuring engine displacement. American car engines are traditionally specified in cubic inches (e.g., a 350 cubic inch V8), though modern specifications often include liters as well.
Current use: The cubic inch is commonly used in the United States for measuring engine displacement in motorcycles, cars, trucks, and other vehicles. It's also used for small container volumes, packaging dimensions, and manufacturing specifications. Converting cubic inches to liters is essential for understanding international engine specifications and comparing American engines to metric engines.
Liter
Definition: The liter (symbol: L or l) is a metric unit of volume equal to one cubic decimeter (1 dm³). One liter equals approximately 61.024 cubic inches. The liter is part of the International System of Units (SI) and is the standard unit for measuring liquid volumes worldwide.
History/origin: The liter was first defined in 1795 during the French Revolution as one cubic decimeter. The name comes from the French "litron," an old measure of capacity. Since 1964, the liter has been defined as exactly one cubic decimeter (1,000 cubic centimeters or 1,000 milliliters).
Current use: The liter is used worldwide for measuring liquid volumes and engine displacements. Modern vehicles typically specify engine size in liters (e.g., a 2.0L or 5.7L engine). Converting cubic inches to liters helps understand engine sizes in metric terms and compare American engines (measured in cubic inches) to international engines (measured in liters).

How to Convert Cubic Inches to Liters
Formula:
1 in³ = 0.016387 L
1 L = 61.024 in³
L = in³ × 0.016387
Quick Approximation:
Divide in³ by 61 for a rough estimate in liters
Or think: 61 cubic inches ≈ 1 liter
Common Engine Conversions:
305 in³ = 5.0 L (5.0L V8)
350 in³ = 5.7 L (classic small block)
400 in³ = 6.6 L (big block)
454 in³ = 7.4 L (large displacement)
Useful Relationships:
1 cubic inch = 0.016387 L = 16.387 mL = 16.387 cc
1 liter = 61.024 in³ = 1,000 mL = 1,000 cc
1 cc (cubic centimeter) = 1 mL = 0.061 in³
Examples:
Convert 350 cubic inches to liters (classic V8):
350 in³ × 0.016387 = 5.735 L
This is a 5.7L engine (common designation: 5.7L V8)
Convert 305 cubic inches to liters:
305 in³ × 0.016387 = 5.000 L
This is exactly a 5.0L engine
Convert 454 cubic inches to liters:
454 in³ × 0.016387 = 7.440 L
This is a 7.4L engine (large displacement big block)
Convert 61 cubic inches to liters:
61 in³ × 0.016387 = 1.000 L
This is exactly 1 liter (perfect conversion point)
Popular Engine Sizes:
Small Block Chevy 350: 350 in³ = 5.7L
Ford 302: 302 in³ = 4.9L
Chevy 454: 454 in³ = 7.4L
Ford 460: 460 in³ = 7.5L
