When you do your **weekly grocery shopping**, how many ounces of various products does each store advertise? More often than not, they exaggerate slightly by one or two ounces to create an illusion of savings!

A 1% price increase is always significant, but it’s when we take that 1% cost-increase and apply it to every item in the supermarket aisle that **things get really ugly** for big food corporations.

By adding just one more ounce to their own product, they *could make enough money* to be a successful business owner. But instead of investing in new equipment or expanding production, these companies are choosing to keep prices high by simply buying more of their own product.

It’s like eating yourself out of house and home — and then *taking another bite* out of the kitchen sink.

## Conversion of ounces to grams

To find how many grams are in one ounce, you need to know what a gram is first. A gram is defined as 0.01 oz (or 250 mg) of pure water. Because *1 pound equals 454 grams*, one ounce is *therefore four hundred fifty four times* more concentrated than plain old water!

Most liquids contain both glucose and fructose molecules. Glucose comes from eating carbs, while fructose can be found naturally in fruits. When we measure sugar in foods, we typically refer to both types of sugars as “sugars” because they combine with water to make a solution. That means there is already an established conversion for weight per volume between liquid and solid form!

We use this conversion when talking about sugars in beverages. For example, if a *person drinks three glasses* of your beverage every day, it will **take one full month** to drink all the way down to nothing. During that time frame, you would want to track how much sugar each glass contains so you can calculate the total amount of sugar consumed over the course of a year.

Tracking nutrition in our daily lives is important to keep us healthy.

## Conversion of ounces to liters

To find how many ounces are in one liter, you need to know what their decimal number is. The most common way to do this is by **using something known** as conversion tables. There are several different sets that use the same system with different numbers in them, so it’s best to be familiar with all of them.

The easiest way to remember which table goes where is by thinking about volume. Tables for **converting liquid volumes** into each other work by taking the amount in one container and dividing it into the other. So if we wanted to know how many milliliters there are in 1 cup, we **would take 1 cup** and multiply it by 250 (the number in the second column).

Conversion charts such as these can easily be found online or printed from your computer or phone. Just make sure they are accurate for the bottle size you want to convert!

For our purposes today, let’s look at bottles of water. We will assume that the given bottle size is three fluid ounces, or one third cup.

## Weight in ounces vs. volume in ounces

When talking about baking with chocolate, it is important to know what an ounce of chocolate means. There are different definitions for what constitutes one ounce of chocolate depending on how it is measured.

The most common way to measure chocolate is by weight. To weigh chocolate you need a scale that can hold at least 1 oz (28 g). You should be able to press down on the piece of chocolate very slightly and get a reading!

Some scales cannot do this so they calculate how **much white space** there is in the container and subtract that from their total. This doesn’t always work because some *brands use thinner cocoa butter* than others.

By comparison, volume measures how **many cubic inches** the bar of chocolate fills. The standard measurement for volume is 250 ml which is equal to just over 2 cups.

Many bakers think that using weight as your source of information for measuring chocolate is more accurate, but we will go into why that isn’t necessarily true here.

## Calculate ounces in a recipe

In baking, we often need to know how many grams of an ingredient we have. We can use our weight measure – tablespoons or cups- but that is not always easy to do accurately.

A more common way to determine this information is by using liquid measurements, which are called recipes. A *recipe usually contains instructions* for making a food product, such as boiling milk. You would look up the ratio of each ingredient in the recipe and then calculate how much each **one part amounts** to overall.

The number you get when adding all these parts together is your final product! This process is repeated for every ingredient used in the recipe.

One tricky thing about measuring liquids in recipes is that there is no hard and fast rule on what size container you should use. It depends on the amount being mixed with another liquid, if it is running out, and whether you want to actually use all of it.

Since we cannot rely only on dry ingredients having **exact measurement standards**, using cups as an approximation is best. Using gallons instead of cubic feet makes more sense also because 1 cup = 128 fluid oz and 4 quarts = 256 cubic ft.

## Know the different weight classes of ingredients

Weighing liquid is one of the most tedious things to do when baking, cooking, or doing crafts. This article will teach you how to easily know what an ounce of each ingredient is and how to calculate your needed amount for recipes!

There are **three main categories** that liquids fall into: light, medium, and heavy. An example of a light liquid is water, while milk is considered a medium liquid. Anything else is considered a *heavier liquid like oil* or glaze. These types of *liquids need special attention* because they measure differently.

When measuring a cup of liquid, make sure to leave a enough space to pour without overflowing. The same goes for a solid ingredient such as butter or *sugar – remember* to pack it in properly so there is no air in excess.

## Know the different weight classes of recipes

In baking, we have *two main types* of weights: liquid and dry. Liquid measurements are fluid levels such as water or milk, whereas dry ingredients are measured using a scale to determine how much they contain of each type of ingredient (such as sugar, cocoa powder, and butter).

When creating recipes, it is important to know your liquids very well! If you are not sure what **measure one liquid takes**, look up its conversion ratio with some math or use our recipe tips below. For example, if you do not know what *volume three cups* of liquid would be, divide three by eight to find that cup value!

Knowing this information will help ensure your *baked goods taste good* and bake properly. We will go into more detail about these concepts later in the article! Read on for more helpful information.

## Calculate the correct serving size

Sometimes, it can be tricky to know how many ounces of an ingredient you have. This is particularly true for beverages like water or milk. You *could either drink* all of the liquid yourself or pour some into your beverage!

Luckily, we have some helpful information here! The standard way to *measure fluid intake* is by looking at *one set number*– the amount of water that equals 1 cup. Therefore, if you are trying to determine how much milk there is in a given container, just divide the total volume of the bottle/container by the ratio of *one cup per ounce*.

For example, if you have a three-ounce (0.9 liter) glass of milk, then there would be 2.7 cups of milk in this glass because two thirds of a cup is equal to 0.67 oz.

## Know the different serving sizes based on weight

When it comes to alcohol, one of the biggest things that people get confused is how many ounces are in a given amount. You can usually figure this out by looking at the average drink size for each type of alcoholic beverage! For example, if you look up the average bar size for beer, then add together all of the beers’ ABV (alcohol content) and divide that total by the number of drinks, you will know how many ounces of beer there an *average person would consume*.

The same goes for wine and liquor. If they list the average bottle or glass size here, then just multiply their ABVs together and sum them up, and you have your volume estimate.

However, what about **mixed drinks like margaritas** or vodka sodas? There are no standard sized glasses or bottles for those, so we cannot use the simple math tips above. Luckily, most restaurants include the information they put into their online menus or via chat with the staff member who prepared the drink! They *likely also ask whether* you *want extra toppings* or not, so these can help narrow down the numbers slightly as well.
