There are certain steps using which conversion of quarts can be done from gallons. The process of conversion of gallons to quarts is  the value, which is multiplied by 4. The process of conversion is simple. For example, it can be taken as the amount of quarts in a gallon is 1.5 which makes 6 quarts for 1.5 gallons.

1 Gallon=4 Quarts

1 quart is equivalent to 0.25 or (1/4) gallon. The process of conversion of quarts to gallons is through multiplying  the value of quarts by 0.25 or simply using the process of division to gather the required results.

Gallon is an United States measurement systems unit of volume. 1 US fluid gallon measurement can be found by 128 US fluid ounces which roughly translates to 3785.41 mili litres “mL” which is denoted by the symbol “gal”.

Quarts is a customary imperial measurement system which is a system unit of volume. 1 US quarts for fluid is around 32 US fluid ounces which is around 946.353 mili litres . The symbol for quart is “qt”.

4 quarts is 1 gallon can be derived from the amount of ounces of fluid each volume measurement, quarts and gallons measure upto.

1 US Gallon = 3785.41 mL

1 US Quarts = 946.353 mL

Therefore, 3785.41/946.353= 4.

Thus, 1 Gallon= 4 Quarts

Or

4 Quarts = 1 Gallon.

1 US Quarts = 0.25 Gallons

Or

2 US Quarts = 0.50 Gallons

Or

3 US Quarts = 0.75 Gallons

Or

4 US Quarts= 1 Gallons.

Most of the world is dependent on the metric system, whereas the United States has structured a non-uniform system for measuring of most of the liquids. A different system of the British imperial units, the United States customary system, in measuring the liquid in different liquid substances or quantity of liquid fluid ounces. The efficient management formulas, calculation cost , the customary necessity of understanding the United States system for the conversion of gallons, quarts, pints and cups.

For changing cups to pints, it should be multiplied with 8 ounces by 2. This denotes that 1 pint holds 16 ounces, where 1 pint equals 2 cups ( 2*8=16), again to convert cups or pints to quarts, it must be noted that there are 32 ounces in a quart, which means a single quart can hold 4 cups (4*8=32) or 2 pints (2*16=32).

Calculation of the number of cup, pints or quarts in a gallon, which shows a gallon holds 128 ounces, a gallon is equal to 16 cups (16*8=128), 8 pints (8*16=128) or 4 quarts (4*32=128). Therefore, it shows that the amount of 4 quarts and 1 gallon is equal to 128 ounces.

1 gallon= 128 ounces,

4 quarts = 128 ounces,

Hence, 1 gallon = 4 quarts or 4 quarts=  1 ounces.

Another representation can be done through,

2 cups = 1 pint (16 ounces)

4 cups (2 pints) = 1 quart (32 ounces)

8 cups (4 pints) = ½ gallon (64 ounces)

4 quarts = 1 gallon (128 ounces).

The United States system of measurement is a generalized procedure in commerce, put forward by International Yard and Pound, the agreement, which was signed in 1959. The metric equivalence given for miles, feet and inches. The liquid quart in United States chart for liquids is 57.75 cubic inches, the value of which is equal to 0.946352946 litres.

1 US liquid quart = ¼ liquid gallons

    = 2 US liquid pints

    = 4 US liquid cups

    = 8 US liquid gills

= 32 US fluid ounces

= 57.75 cubic inches

= 0.946352946  litres

= 33.307 imperial fluid ounces

The dry quart in US has a value of, which is equal to ¼ of a US dry gallon, the value of which is 1.101220942715 liters.

The calculation is given by,

1 US dry quart = 1/32 US bushels

= 1/8 US pecks

= ¼ US dry gallons

= 2 US dry pints

= 67.2 cubic inches

= 1.101220942715 litres

= 38.758 imperial fluid ounces

The calculation can be derived from,

1 quart = 0.94635 liters

0.94635 liters = 946.35 milliliters

231 cubic inches = 128 ounces

128 ounces = 8 pints

8 pints = 4 quarts

4 quarts = 1 gallon

1 gallon = 3.785 liters

Thus, from the above calculation it can be derived that 1 quarts equals ¼ gallons, thus value of 4 quarts is equal to 1 gallon in the US metric system of calculating volume of a liquid substance which is the international standard taken from United States chart value of liquids.
