Ever needed to know how many cups are in a half gallon? Us, too! It can be so confusing to try to remember all of the many, many, many measurement conversions in cooking and baking.

It’s especially confusing when you go from a pretty small unit, like a cup, to something much bigger, like a half gallon.

Sometimes you find a recipe that calls for one unit of measurement, but the food at the grocery store is packaged using different units, so you have to convert.

Or maybe you are scaling a recipe up or down, and having a different set of units would be useful.

My husband’s family has a beloved hot cocoa recipe he likes to make every holiday season that calls for a full gallon of milk. That’s too much for just our little family to drink.

In a case like this, it’s helpful to know how many cups are in a gallon or how many cups are in a half gallon of milk so that we can make a more manageable amount of cocoa for our kids.

Or perhaps you’re mixing drinks for a party and need to know how many shots are in a half gallon or how many shots are in a bottle. We’ve got you covered!

Below you will find several measurement conversions that you may find handy when cooking or baking.

## What Is a Gallon?

We all know what a gallon is when we think about a gallon of milk, but what is a gallon? Very simply, it is a unit of measurement most often used to measure liquids by volume.

Traditionally, a gallon measurement was often used to measure dry goods as well, but that practice is no longer standard.

## How Many Cups in A Half Gallon

There are 8 cups in a half gallon. To know how many cups are in 1 gallon, simply double that measurement. There are 16 cups in 1 gallon.

## How Many Quarts Are in a Gallon

The term "quart" refers to a quarter of a gallon. Since 1 quart is a quarter of a gallon, 4 quarts make 1 gallon. By the same standard, there are 2 quarts in a half gallon.

## How Many Cups Are in a Quart

Each quart, or quarter of a gallon, measures 4 cups. Knowing this, we also know that there are 8 cups in 2 quarts, which is also equivalent to a half gallon as noted above.

## Other Cooking Measurement Conversions

There are lots of conversions I find particularly useful when I’m in the kitchen baking and cooking, such as how many teaspoons equal a tablespoon.

Sometimes you need to know how many fluid ounces are in a cup or even how many cups are in a pound of flour.

Here are some of the other conversions I use most often:

- 1 Tablespoon = 3 teaspoons
- 4 Tablespoons = 1/4 cup
- 8 Tablespoons = 1/2 cup
- 16 Tablespoons = 1 cup
- 2 Tablespoons = 1 fluid ounce
- 1 pint = 1 lb (“A pint’s a pound the world around”)
