How to use the engine size converter

Enter the engine displacement you want to convert, such as cubic inches from a US spec sheet or liters from an international listing.

Choose the source unit you already have, then switch the target unit to cubic inches or liters.

Use the result to compare engine families, read parts listings, or translate specs across different automotive markets.

Displacement formulas

Engine displacement is a volume. This converter focuses on translating published displacement values between cubic inches, cubic centimeters, and liters.

1 cubic inch = 16.387064 cc
1 cubic inch = 0.016387064 L
1 L = 61.023744 cubic inches

Common engine-size checks

350 ci small-block

5.74 L

Often rounded and discussed as a 5.7 L engine family.

302 ci V8

4.95 L

Useful when comparing classic cubic-inch names with metric listings.

6.2 L engine

378.35 ci

Useful when reading US parts discussions or older performance references.

Automotive context notes

Marketing names may round displacement, so a listed 5.7 L engine may not equal exactly 5.700 L internally.
Bore, stroke, cylinder count, and factory family codes matter for parts fitment beyond the converted size.
For registration, emissions, racing classes, or swap legality, verify the value against official vehicle or engine documentation.

Helpful when displacement needs liters or cubic inches

Useful for classic and modern engine specs

Good when one source lists a motor in cubic inches and another lists the same kind of engine in liters.

Easy to compare nearby engine sizes

Change the value and see the converted displacement update immediately.

Works for listings, swaps, and parts research

Helpful for engine identification, spec comparison, parts compatibility checks, and cross-region research.

Quick in the garage or on the go

Useful while checking car listings, engine builds, swap notes, or parts pages from your phone or desktop.
