Both a gallon(gal) and quarts(qt) are units of capacity.
A gallon is used to measure very large volumes of liquids.
Three kinds of quarts are currently used: the liquid quart and dry quart of the US customary system and the imperial quart of the British imperial system. All are roughly equal to one liter.
Formula to convert gal to qt.
To convert gal to qt, we need to know how they are related.
We say that 1 gallon is equal to 4 US quarts.
Therefore, to convert gallons to qt, we multiply the gal by 4.
Capacity in qt = Capacity in gal x 4
Convert 25 gallons to quarts.
= 25 x 4
= 100 quarts.
