## What is gallon (gal)?

When working with the United States customary system for liquid measurement. it is always handy to use a memory tool. Begin with a capital G for one gallon. Within the G right four cues for quarts. This represents 4 quarts in gallon. A quart is called a quart since it is a quarter of a gallon. Just as one 25 cent coin is a quarter or ¼ of a dollar. Within the cues right to peas four pints. This shows that there are two pints in a quart for a total of eight pints in a gallon. Continue on to write 2 C’s inside of each P the C stands for cup. There are 16 cups in a gallon. The memory tool is now complete. Showing the capital G is 1 gallon. A gallon is made up of 4 quarts or 8 pints or 16 cups. and 1 gallon is 3785.41(ML). This is the right answer that what is a gallon.

## What is litre (L)?

We’re here to talk about one liter equals to how many gallons. Now I’m sure you’ve seen liters and gallons before when it comes to you know shopping for groceries or a connivance store things like that. You’ve seen I think more and more the 1 liter bottles of water or soda and you’ve also seen gallons of me half a gallon on one full gallon but you probably have suspected when it comes to looking at those beverages that a liter is less and smaller than a gallon. So in terms of conversions you have two completely different kinds of numbers here. But the one thing I want to keep in mind it will take a little getting used to is the fact that (1L = 0264gallons) that’s right one liter is actually just a little more than a quarter of a gallon. So basically one gallon is going to be around four liter. So that pretty much answers the question for you. One liter is equal to how many gallons.
