About the Quart

Facts & Uses

  • US liquid quart = 946.352946 mL exactly (= ¼ US gallon = 2 US pints = 32 US fl oz). The bridge between pints and gallons.
  • Common for oil bottles (motor oil, cooking oil), milk cartons, mason jars, and paint cans in the US market.
  • UK imperial quart = 1136.5225 mL exactly — about 20% larger; rarely used today as the UK favors liters.
  • Slow cookers, soup pots, and storage containers commonly sized as 2-quart, 4-quart, or 6-quart.

Curiosities

  • The name "quart" comes from "quarta pars" — Latin for "fourth part" of a gallon, dating back to medieval English measures.
  • A US dry quart (1.101 L) also exists for measuring fruits and grains, but is functionally obsolete outside agricultural commodity reports.
  • 1 US quart of water weighs ≈ 2.086 lb at room temperature — a quarter of a gallon's 8.34 lb.
  • Approximate equivalents: 1 US qt ≈ 0.946 L ≈ 0.833 imperial quarts ≈ 32 fl oz.
