In US Customary system and British Imperial system of measurements, Quart is a unit capacity of measurement. For dry and liquid both measure, the British Imperial system uses the standard quart measurement that is equivalent to two British Imperial pints or equal to 1/4^th of Imperial gallon. The US customary system has two measurement units, which is known as quart. One unit is for dry measurements, which is slightly larger and another one unit is for liquid measurements. The quart is equivalent to 2 fluid pints and 1/4^th of US gallon. The dry quart is equivalent to two dry pints. A quart is a unit of medieval English for liquid and dry measurement, which lies between 0.95 and 1.16 of liters.

Quart is denoted as ‘qt’. Quart is parted into four cups or two pints. The accurate size the quart has various values of gallon. There are quarts of three kinds such as dry quart of US customary system, liquid quart and imperial quart of British imperial system. All the quarts are roundly equivalent to one metric liter.

One quart is liquid unit of volume and it is nearly equal to one- fourth of two pints or an gallon. Two different types of measurements are there in quarts. One is the US liquid quart and another one is UK imperial quart. One quart is equal to four cups in US and UK measurements.  For US traditional system, one fluid quart has 32 liquid ounces of volume, which is equivalent to 946.35 ml and one cup is equal to eight liquid ounces of volume unit, which is equivalent to 236.588 ml. this makes 32 to be divided by 8, which is equal to 4 cups in the US quart. In one UK imperial system has 40 liquid ounces of unit, which is equivalent to 1136.52 ml and the cup of imperial unit volume has the limit of 10 imperial fluid ounces, which is equivalent to 284.131 ml. this makes the 40 to be divided by 10, which is equal to 4 cups in the UK quart system. By this theory it can be decided that the UK quart is large than the US quart of measurement.

Quart is emerged on gallon. This definition has changed over the history, which is emerged on the commodity of being referenced. The recent definition of the quart is emerged on the British wine gallon. This similar definition was used in the UK redefined for the imperial quart. The recent uses of quart is give the measurements of the US and UK liquid and dry objects.

US liquid quart: In the US, all the customary volume and length measurements have been standardized legally by the international yard and pound agreement in 1959. It uses one yard to get 0.9144 meter. By the definition, it is derived the equivalencies of metric for the feet, inches and mile. 57.75 cubic inches is equivalent to the US liquid quart and that is accurately equal to 0.946352946 liter.

• One US liquid quart is = one-fourth of US liquid gallons

= 2 of US liquid pints

= 8 of US liquid gills

= 32 of US fluid ounces

= 4 of US liquid cups

= 57.75 of cubic inches

= 33.307 of imperial fluid ounces

Equivalent to 0.946352946 of liters

• One US dry quart is = one-fourth of US dry gallons

        = One-eighth of US pecks

                        = 1/32 of US bushels

        = 67.2 of cubic inches

        = 2 of US dry pints

        = 1.101220942715 of liters

        Equivalent to 38.758 of imperial fluid ounces

• One imperial quart is = one-fourth of imperial gallons

          = 40 of imperil fluid ounces

          = 2 of imperial pints

          = 1.1365225 of liters

          Equivalent to 38.430 of US fluid ounces

          Equivalent to 69.355 of cubic inches

In Reputed quart, the quart is measurement of an imperial quart that is equivalent to two third of imperial quart. It is also equal to 1/6^th of the imperial gallon. It is near about 0.7577 liter. Reputed quart was a standard size of a wine bottle previously in the UK and it was slight larger than the recent size of the wine bottle, which is about 0.75 of liter in standard size.

In Winchester quart, the quart is a measurement of an archaic measure, which is nearly equivalent to two of imperial quarts. The measurement of Winchester quart is 2.25 in liter. An example of Winchester quart is the laboratory bottle for chemical supply, whose size is 2.5 liter. It is slight larger than a customary Winchester quart.

Five basic units of measurements are there to measure the capacity in US traditional measurement system. These basic five units are quart, cup, pint, gallon and ounce. These units of measurements are connected to each other. Using these measuring units, the capacity of any liquid or dry object can be described. Gallon is used to describe the larger units and cups, quarts and pints are used to measure smaller unit of any object.

Gallon is the US customary and imperial system to measure unit of volume. Four unit of US dry quarts are equal to one dry gallon.  Four units of US liquid quarts are equal to one liquid gallon. Four imperial quarts are equal to one imperial gallon. Value of the gallon is various, which is depending on the region of geographical area. 4.55 liters is equivalent to imperial gallon and 3.79 liters is equivalent to US liquid gallon. For measuring the fuel, gallon is mainly used. One quart is equal to one-fourth of a gallon. 1.1 liters is equal to the US quart and 1.14 liters is equal to one imperial quart. The word gallon comes from the word ‘galon’ in the Old Northern French and it is developed as the system of measure the beer and wine in UK. It gives results in wine gallon, imperial gallon and ale gallon. In the US, it is mainly used for measuring the unit. Gallon is used to measure larger unit like larger container, ice cream tube or cartons of milk. All these things are measured using gallon. In United States and the other US territories, gallon is greatly used in the fuel economy. Imperial gallons are hugely used than the US gallons in the many countries using the measurement of liter during referencing the fuel.
