Liters, gallons, and quarts

  • US gallons and quarts — not imperial. 1 US gal ≈ 3.785 L; 1 US qt ≈ 0.946 L.
  • Oil fills, fuel cells, and coolant capacities mix quarts and liters on the same shelf.
  • Cubic inches on this board are a volume. Engine badges are easier on the displacement converter.

Fluid catalogs do not pick a side. A 5 qt oil fill, a 16 gal cell, and a 6.2 L coolant spec can appear in one afternoon. This converter uses US gallons and quarts (the ones on a US parts-store jug), liters, milliliters, and cubic inches.

Imperial gallons are larger (~4.546 L) and are not on this board. If a UK paper says gallons, do not run it through the US gal tile.

For “5.7 L to cubic inches” as an engine size, the displacement converter is written for that job. This page is the fluid and capacity tool that happens to share the same volume math.

When this is the wrong tool

Engine badge liters ↔ ci is clearer on the displacement converter. Bore × stroke is the engine displacement calculator. Injector flow in cc/min is a rate, not a tank volume.

How to convert liters and gallons

  1. Enter the capacity. Jug, cell, or service-manual fill.
  2. Pick L, gal, qt, mL, or ci. US gallons and quarts only.
  3. Read the board. Tap a tile to put that unit on the right-hand card.
