What is US Measurement?

A measurement is a number that describes the size or amount of something. You can measure many things like area, length, capacity, weight, temperature, and time. In the United States, there are two main systems of measurement: the metric system and the U.S. customary measurement system.


What is Volume?

Volume measures capacity. For example, the volume of a container can be defined as the amount of space inside the container or how much water, for example, it would take to fill the bowl.

In the US customary system of measurement, the most common units of volume that are in use are as follows 

  1. Cups

  2. Pints

  3. Quarts

  4. Gallons.

Volume measurement can be usually used with liquids as well as with fluids because such items are difficult to weigh. Volume is often the measure used when portioning sizes of the finished products. 

The most commonly used units of measurement in the U.S. systems and imperial systems are shown in the given table below.

How Big are Customary Units of Volume?

A juice box contains almost one cup of any liquid.

A pint is equal to two cups. A water bottle or a container contains about one pint of liquid.

A quart is equal to two pints. A large shampoo bottle/container contains about one quart of liquid.

A gallon is equal to four quarts. A milk jug contains about one gallon of liquid.


Converting Larger Units to Smaller Units

1 pint =2 cups

1 quart =4 cups

1 quart =2 pints

1 gallon= 4 quarts

We can easily convert larger units to smaller units by multiplying the number of larger units by the green conversion factor for the various appropriate smaller units.


Converting Gallons to Quarts

1 gallon is equal to 4 Quarts

2 gallon equals 2*  4 Quarts equals 8 Quarts

3 gallon equals  3*  4 Quarts equals 12 Quarts

4 gallon equals  4*  4 Quarts equals 16 Quarts


Converting Between Units in the Imperial and the U.S. Systems

On occasion, there may be chances you may need to convert between the various units of volume and between units of weights and units of volume in the U.S. system. To do this, you must know the equivalents for each of the units as shown in the table given below
