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).

What is the Barrel?

The oil barrel equals exactly 42 US gallons (158.987 liters) and is the global benchmark unit for crude oil pricing and trading. The 42-gallon size dates to the 1860s Pennsylvania oil boom, when oil was shipped in repurposed wooden barrels of various sizes; the standard settled at 42 gallons as a practical industry compromise. Today, the oil barrel is virtually synonymous with crude oil — Brent crude and WTI prices are quoted per barrel ($/bbl), OPEC tracks production in barrels per day, and proven reserves are listed in billions of barrels. Despite metrication, the barrel persists in petroleum trading and journalism worldwide. It relates to the US gallon (1 bbl = 42 US gal), the cubic meter (1 bbl ≈ 0.159 m³), and the liter (1 bbl ≈ 159 L). Note that beer and wine barrels have different volumes.
