Barrel (Oil): is a globally recognized unit of volume used to measure crude oil and other petroleum products. Although the actual liquid is not typically stored in barrels today, the term remains a standard in the oil industry for pricing, production, and trade. The size and definition of the oil barrel can vary slightly depending on the measurement system, but the most commonly used standard is the U.S. oil barrel.
1 oil barrel is equal to 42 U.S. gallons or 158.987 liters. Quart (US liquid): unit of volume in the U.S. customary system, commonly used to measure liquids. The name "quart" comes from the Latin word quartus, meaning "fourth," as a quart is traditionally one-fourth of a gallon.
The U.S. liquid quart is abbreviated as "qt" and 1 U.S. liquid quart is 32 U.S. fluid ounces which is 946.352946 milliliters.
