About These Units
Volume measures three-dimensional space — how much liquid a container holds, or how much air is in a room. The metric system uses liters and cubic meters; the US uses cups, gallons, and fluid ounces (which differ from US Imperial gallons — UK 1 gallon = 4.546 L vs US 1 gallon = 3.785 L). This tool uses US gallons by default. Volume conversion is crucial for cooking, fuel economy, brewing, chemistry, and shipping container sizing.
About Milliliters
The milliliter (mL) is 1/1,000 of a liter, equal to one cubic centimeter.
Part of the original metric system; one milliliter of water weighs exactly one gram.
Used for medicine doses, cooking, cosmetics, and small liquid containers.
About Gallons (US)
The US gallon is exactly 3.785 liters (4 quarts or 128 fluid ounces) — the standard fuel and large-liquid unit in the US.
From medieval English measurement; the US gallon differs from the UK imperial gallon (4.546 L).
Used for gasoline in the US (price per gallon), milk jugs, paint cans, and water heater capacities.
When Conversion Is Needed
Milliliters and Gallons (US) belong to different measurement systems, so conversion becomes necessary when comparing values across the two units, or when forwarding a document or specification written in one unit to someone who uses the other. The quick-reference table on this page shows how common values in Milliliters translate to Gallons (US), so memorizing or bookmarking the most frequently-used values is often a worthwhile shortcut.
Real-World Use Cases
Cooking & Bartending
Translating recipes between cups (US), milliliters (Europe), and tablespoons requires careful volume conversion. A 'cup' in the US (240 mL) differs from a UK 'cup' (284 mL), so check the recipe's origin.
Fuel & Travel
Gas prices are quoted per gallon in the US, per liter elsewhere. Converting helps compare costs across borders. 1 US gallon ≈ 3.785 liters, so a $4/gal price equals about $1.06/L.

Frequently Asked Questions
Are US and UK gallons the same?
No — a US gallon is 3.785 liters, a UK (Imperial) gallon is 4.546 liters. That's why a 'mpg' figure from a UK car magazine looks better than a US one for the same fuel economy. This tool uses US gallons.
How many cups in a liter?
1 liter ≈ 4.227 US cups, or 4.4 UK cups. For practical cooking, 1 liter ≈ 4 cups + 1 tablespoon (US measure).
Why does a 1L water bottle weigh 1 kg?
Pure water at 4°C has a density of exactly 1 g/mL by historical definition. So 1 liter = 1 kg of water. Other liquids differ — milk is ~1.03 g/mL, gasoline ~0.74 g/mL.
