What Is a Quart?
The US liquid quart (qt) is a customary unit of volume equal to ¼ gallon, 2 pints, or 32 fluid ounces (946.353 mL). It is used in the United States for milk, broth, cooking, and automotive fluids. The UK imperial quart is larger at 1,136.5 mL.
What Is a Liter?
The liter (L) is a metric unit of volume equal to 1,000 milliliters or 1 cubic decimeter. It is the global standard for liquid measurement in cooking, commerce, and science. One liter equals approximately 1.057 US quarts.
Quarts to Liters Formula
The conversion factor is:
liters = US quarts × 0.946353
Derived from: 1 US qt = 32 fl oz = 946.352946 mL = 0.946353 L.
Worked Example
Convert 4 quarts (1 US gallon) to liters:
- Multiply: 4 × 0.946353 = 3.785 liters
So 1 US gallon (4 quarts) = 3.785 liters — the well-known gallon-to-liter conversion.
Quick Estimation
1 quart ≈ 1 liter minus 5%. A quart is about 95% of a liter. For quick math: treat them as equal, then subtract 5%. Example: 6 quarts ≈ 6 liters minus 5% = 5.7 L (exact: 5.678 L).

Which Is Bigger: Quart or Liter?
A liter is 5.7% bigger than a US quart. One liter = 1,000 mL, while one US quart = 946 mL — a difference of 54 mL (about ¼ cup). For rough kitchen estimates, they are nearly interchangeable, but the difference matters at scale: 10 quarts = only 9.46 liters, not 10.
When You Need This Conversion
- Adapting US recipes: A recipe calling for 2 quarts of stock = 1.89 liters. When buying metric containers, a 2-liter carton slightly overshoots.
- Canning: US canning recipes specify quarts. A quart jar = 0.946 L, so a 1-liter metric jar is slightly larger.
- Automotive: US oil capacities are in quarts; European manuals use liters. A "5-quart oil change" = 4.73 liters.
