Tips

Use these in everyday conversions
  • 1 US quart = 2 US pints = 946 ml ≈ 1 L.
  • 1 UK quart = 2 UK pints = 1137 ml.
  • Quarts appear more often in the US than UK in everyday usage.

Common Mistakes

Avoid these
  • Treating US and UK quarts as equal — 20% off.
  • Using quarts outside US — most metric countries do not use them at all.
  • Confusing quart (volume) with quarter (mass unit in older UK contexts).

About Quart and Cubic Inch

What is the Quart?

The US quart equals exactly one quarter of a US gallon (0.946352946 liters) and is a common kitchen and motor-oil volume in the United States. The word 'quart' derives from the Latin 'quartus' meaning fourth. Milk and motor oil are commonly sold in quart containers (a quart of motor oil is 32 fl oz), and large recipes call for quart-sized stockpots. The US quart is distinct from the slightly larger UK imperial quart (1.137 L). It relates to the gallon (4 qt = 1 gal), the pint (2 pt = 1 qt), the cup (4 cups = 1 qt), the fluid ounce (32 fl oz = 1 qt), and the liter (1 US qt ≈ 0.946 L). The quart is a useful intermediate volume between the cup (small recipe measurements) and the gallon (bulk liquids).

  • US cooking recipe quantities
  • US motor-oil container sizes (1 quart bottles)
  • Canning and preserving containers
Real-world examples

A US quart of motor oil is 946 ml. A "quart of milk" in the US ≈ 1 L. UK "quart" is rare today.

What is the Cubic Inch?

The cubic inch equals exactly 16.387064 cubic centimeters and is the traditional American unit for engine displacement and small-volume manufacturing measurements. Classic American muscle cars were famously identified by their cubic-inch engine size: the Ford 'Boss 429' had a 429-cubic-inch (7.0-liter) V8, and the Chevrolet 'Big Block 454' was 7.4 liters. Modern American automakers have transitioned mostly to liter-based naming (e.g., 'Hemi 5.7'), but the cubic inch persists in vintage car culture and aviation engines. It is also used for printer-paper coverage and industrial tolerances. The cubic inch relates to the cubic foot (1,728 in³ = 1 ft³), the cubic centimeter (1 in³ ≈ 16.39 cm³), the milliliter (1 in³ ≈ 16.39 mL), and the US fluid ounce (1 fl oz ≈ 1.805 in³).

  • Classic US car engine displacement
  • Firearms chamber and cartridge specs
  • Some US machining and mould design
Real-world examples

350 cu in V8 = 5.7 L engine. 302 cu in Ford V8 = 4.9 L. Modern specs typically give litres.
