How Do You Convert Quarts to Liters?
Multiply the number of US quarts by 0.946353 to get liters. The formula is: Liters = US Quarts x 0.946353. To convert back from liters to quarts, divide by 0.946353. This conversion uses the US liquid quart (32 US fluid ounces), not the UK imperial quart (40 imperial fluid ounces), which is about 20% larger.
Marco Ferreira at his restaurant in Pinewood Falls makes chicken stock in large batches. His grandmother's recipe from Italy calls for 6 liters of water, but his stock pot is marked in quarts. He divides 6 by 0.946353 to get 6.34 quarts, so he fills just past the 6-quart line. When scaling down a recipe that calls for 2 quarts of broth, he knows that equals 1.893 liters -- just under two of the 1-liter cartons at the grocery store.

When Do You Need This Conversion?
Cooking and Baking
Quarts appear constantly in American recipes, while most of the world measures in liters. Leah Novak at her bakery in Pinewood Falls often adapts European pastry recipes for her American kitchen. When a French custard recipe calls for 1.5 liters of milk, she knows that equals about 1.59 quarts, so she measures out 1 quart plus a generous half-cup more. For her large-batch lemonade that calls for 3 quarts of water, she tells her assistant visiting from Montreal to use 2.839 liters.
Automotive and Engine Fluids
Engine oil capacity is listed in quarts in the US and liters internationally. If your car takes 5 quarts of oil, that equals 4.73 liters. When buying oil abroad or following a European vehicle manual that lists capacity as 4.5 liters, you need 4.76 quarts. Coolant, transmission fluid, and brake fluid all use the same conversion.
Science and Lab Work
Scientific measurements use liters and milliliters exclusively. A student measuring 2 quarts of a solution for a chemistry experiment needs to record it as 1.893 liters (or 1,893 mL) in their lab notebook. The slight difference between a quart and a liter -- about 54 mL -- can matter in precise chemical reactions where concentration affects results.
