Question: How many quarts in a gallon?
Answer: There are 4 quarts in a gallon.
Why are there 4 quarts in a gallon?
A quart has 4 cups.
A gallon has 16 cups.
So, 4 × 4 = 16.
In other words, a gallon has 4 quarts.
And just what is a quart?
A quart is actually an abbreviation for “quarter gallon” (and stems from the Latin word “quartus”), which explains the above answer: a quart is a quarter of a gallon, meaning that there are 4 quarts in a gallon.
Be aware, though, that there are different kinds of quarts: a liquid quart, a dry quart (both of which are used in the United States), and an “imperial quart” (which is used in the United Kingdom).
In terms of its closest metric equivalent the liter, a liquid quart is slightly less than a liter (in fact it’s about 0.95 liters).
A dry quart, on the other hand, is actually slightly larger than a liter: it’s about 1.10 liters. Dry quarts are actually used to measure bushels of dry stuff, for example wheat.
And the UK’s imperial quart is the biggest of the three: it’s equal to about 1.14 liters.
What about gallons?
Believe it or not, the same pattern applies to gallons: a liquid gallon is smaller than a dry gallon, which is smaller than a UK “imperial gallon.”
A US (liquid) gallon is about 3.79 liters, a US dry gallon is 4.4 liters, and an imperial gallon is 4.55 liters.
