# How many Quarts are in a Gallon 82 / 100

How many Quarts are in a Gallon – The clue is in the question. Quart comes from quarter. Now I wonder what a quart is a quarter of …

You did basic math, right? So you need to compute the following algorithm

4 quarts equal 1 gallon.

Whether you are talking a US gallon or an Imperial gallon, the term ‘quart’ refers to a ‘quarter of a gallon’, so the answer will always be four.

## How many Quarts are in 40 Gallons ?

A conversion factor is the number or formula you need to convert a measurement in one set of units to the same measurement in another set of units. The number is usually given as a numerical ratio or fraction that can be used as a multiplication factor. Since a conversion factor is always equal to 1, you can always multiply by it. The only thing that changes is the units.

A criticism of the Imperial system, the one which uses gals and qts, is that you need conversion factors within the system. For example, if you don’t know how many oz are in a qt, you‘re stuck. A proposed solution is to use the metric system, in which 1 kilometer = 1000 meters and 1 kilogram = 1000 grams so the conversion factors within the system are trivial

However, when you end up using both systems in tandem, you often see the need for compound conversino factors. For example, how many liters in a 40 gallons Then you could use (4 qts / 1 gal) and (0.946 liters / qt). However, since each of these conversion factors is equal to 1, you can chain as many of them as necessary.

TL;DR:

The conversion factor is (4 qts / 1 gal), so

40 gals * (4 qts / 1 gal) = 160 qts
