1 barrel how many gallons

The API standard for pressure is This is considered the base condition for a standard amount of oil that occupies one barrel of oil. If the pressure is higher or lower, the volume would remain the same, but the mass would change. The indicator of the lightness or heaviness of the oil is the API gravity , which is measured as the inverse of the density relative to water.

Oil is bought and sold based on volume and API density at standard conditions. Keep reading to learn more about each unit of measure. The beer barrel is a standard unit of volume for importing beer in the US, equal to 3, fluid ounces. Kegs in the US are often sized in portions of the beer barrel such as the half-barrel keg or quarter-barrel keg. The beer barrel is a US customary unit of beer volume.

The capacity of a barrel is often measured in gallons. To find how many gallons are in the barrel, simply convert the total volume to gallons. You can find how many liters are in a barrel just like finding gallons. Barrels come in many shapes and sizes, but there are some standard sizes used in industry. Barrels are generally used to store beverages such as wine, beer, and liqueurs. They are also very commonly used to store oil and chemicals. The gallon barrel became a familiar 19th century container.

Then came Edwin L. The petroleum exploration and production boom that followed it consumed wooden tierces, whiskey barrels, casks and barrels of all sizes.

A guild, the Worshipful Company of Coopers, prescribed the manner of construction for a watertight barrel. Lesser skilled craftsmen — slack coopers -made casks and pails for dry goods. When filled with crude oil instead of fish or other commodities, a gallon tierce weighed more than pounds — about as much as a man could reasonably wrestle. Twenty would fit on a typical barge or railroad flatcar. Bigger casks were unmanageable and smaller were less profitable.

The gallon standard oil barrel was officially adopted by the Petroleum Producers Association in and the U.
