Volume Measurements in the US Customary System

US Customary Units of Volume

Volume measures capacity occupied by liquid, solid, or gas. Gallons, quarts, pints, cups, fluid ounces, tablespoons, and teaspoons are used to measure volume. We need to use liquid measuring cups and spoons for basic liquid measurements and conversions. Remember, there are weight measuring cups too, and make sure you use the correct one.

The most significant units of volume in the US Customary System of Measurements are,
  1. cups
  2. pints
  3. quarts
  4. gallons
We use these for liquid measurements every single day. Whether we're cooking, gardening, or filling a pool, we have to know the right unit to use. If you're trying to fill a swimming pool, you're probably going to want to use a gallon more so than you would want to use a cup. Remember, a cup is a small amount, and a gallon is quite large. When you're cooking, chances are you're probably going to use more cups and pints than you are going to use a gallon unless you're making a large amount of something. Therefore, if you measure the water in the aquarium, you measure it with a gallon. If you're measuring the amount of soup that you're making is probably a cup.

You definitely have to know the right unit of volume to use. If you're not careful, you can end up putting too much something into your recipe, and it can lead to a disaster.

What is a Gallon?

A gallon is a relatively large amount of volume. It's a lot, a gallon is 128 fluid ounces. Some people try to drink a gallon of water every day. It's a lot of water to try to drink.

If you go to a party and somebody asks you to bring a drink, you're probably going to bring a gallon size of lemonade or kool-aid or something like that. 

What is a Barrel?

A barrel is a unit of measurement of oil volume. North America is using this unit to measure crude oil or other petroleum products. Crude oil, also known as black gold is pumped each and every day in almost 100 million barrels and then shipped to refineries for processing. Most oil companies ship their oil in barrels that always contained exactly 42 U.S. gallons. 

What is the abbreviation for the barrel?

The barrel is abbreviated as bbl.

How to Convert Barrels to Gallons? 

To convert barrels into gallons you have to multiply the barrel value by 42.

Example:

Convert 5 barrels (5 bbl) into gallons (US).

We know that 1 bbl = 42 gal
Therefore, 5 bbl = 42 gal x 5
Therefore, 5 bbl = 210 gal (US)

I.e. there are 210 gallons (US) in 5 barrels.

Why 42 gallons in a barrel of oil?

The 42-gallon barrel was the preferred type of container to store and transport crude oil out of Pennsylvania by the year 1860. After that, a small group of oil well owners adopted the 42-gallon barrel as their preferred type of container by the year 1866. Moreover, the Petroleum Producers Association declared the 42-gallon barrel as the industry standard for petroleum products in the year 1872. Finally, after ten years, the U.S. Bureau of Mines and the U.S. Geological Survey adopted the 42-gallon barrel as an official unit of measure in the year 1882.

How many gallons is a 55-gallon drum?

A 200-liter drum (known as a 55-gallon drum in the United States and a 44-gallon drum in the United Kingdom) is a cylindrical container that has been used for centuries for the transport of solid and liquid goods. Don't get confused over the 55-gallon drum. All the 55-gallon drums don't have the same capacity despite their name. The exact capacity can depend on the manufacturer and what the drum is going to be used to carry. The average 55-gallon drum is usually of size around 35 inches in height and 23 inches in diameter. Sometimes there may be slight variations of those values.

Why is the modern metal drum 55 gallons?

As the 55-gallon drum could be moved with a tilt truck, rolled on its edge, or on its side, all without mechanical assistance, it was deemed the largest capacity vessel that could be easily maneuvered manually. These are made from plastic, fibers, steel, stainless steel, and other materials, the 55-gallon drum nowadays has been designed to last and be able to withstand the conditions met in long-haul shipping.
