Liters to cubic inches for engine badges
1 liter ≈ 61.02 cubic inches. A 5.7 L badge is about 348 ci; a 350 is usually a 5.7 that was rounded the other way.
1 L = 1,000 cc = 1,000 mL. “350 ci” and “5.7 L” are marketing roundings of the same volume class.
This converts a published displacement. It does not compute displacement from bore, stroke, and cylinders.
Crate engines, auction listings, and swap threads bounce between liters and cubic inches. This page is the badge converter: type 5.7 L and read ~348 ci, or type 350 ci and read ~5.74 L. That is volume, not a build sheet.
OEMs round. A “5.3 L” GM truck mill is not a clean 323 ci in every year, and a “350” small-block is a family of bores and strokes that land near 5.7 L. If you have the actual bore, stroke, and cylinder count, use the engine displacement calculator — that is the real number, this page is the catalog number.
cc and mL are the same volume. A 2,000 cc four-cylinder is a 2.0 L, not a 2,000 ci V8.

When this is the wrong tool
Bore, stroke, and cylinder count belong on the engine displacement calculator. Oil fill and fuel-cell gallons belong on the volume converter. Compression ratio is a different page entirely.
How to convert liters to cubic inches
Enter the badge. Use the liters or cubic inches printed on the listing or valve cover.
Set L or ci. Do not enter cc as if it were cubic inches — 2000 cc is 2.0 L, not 2000 ci.
Read the other badge. The board also shows mL, gallons, and quarts if you need a fuel-cell cross-check.
Displacement converter FAQ
5.7 L ≈ 348 ci. A “350” small-block is the same size class, rounded the other direction (350 ci ≈ 5.74 L).
350 cubic inches ≈ 5.74 L. Marketing often prints 5.7 L for that family.
Yes. 1 cc = 1 mL. A 1600 cc motorcycle engine is 1.6 L. It is not 1,600 cubic inches.
Badges are rounded. Punch bore, stroke, and cylinder count into the engine displacement calculator for the geometric volume.
