So, when you need to determine how many grams in an ounce, you just need to use our simple converter that is located at the top of this page. After all, our how many grams in an ounce converter will allow you to make the conversion that you need between these imperial and metric units.
As a side note, it was back in 1958 that the United States and the countries of the Commonwealth (New Zealand, Australia, and Canada) defined the mass of the international avoirdupois ounce as being equal to 28.3495 grams.
While you can simply use our how many grams are in an ounce converter to make this conversion, we believe that it is important that you understand a bit more about these two units of measurement. In our opinion, this will help you not only making your conversions faster but also understanding the relationship between these two units of measurement.
What Is A Gram?
Simply put, a gram which is normally represented using the letter g, is a unit of mass in the International System of Units (SI).
One of the things that you need to understand about the gram is that it is based on the kilogram. In fact, a gram is one-thousandth of a kilogram, which is the International Systems of Units base unit of mass. While the kilogram is now the base of the SI, the truth is that this hasn’t always been the case. The reality is that the gram used to be a crucial unit of mass that was a part of the centimeter-gram-second systems that was used until the adoption of the International System of Units (SI).

Nowadays, the gram is extremely used not only for cooking or baking but also in scientific contexts. Besides, it is worth pointing out that most standards on the nutrition labels of food products usually require the relative content to be stated per 100 grams of the product.
What is An Ounce?
An ounce, which is commonly referred to as oz, is also a unit of mass. However, the ounce is a unit of mass that is part of both the United States Customary System and the Imperial or British Measurement System.
Note that the ounce is not always the same and when it is referred to as the avoirdupois ounce, we are referring to the common ounce.
The ounce is equal to 28.349523125 grams and it is also equivalent to one-sixteenth of an avoirdupois pound or 16 drams.
While the ounce is very used in countries such as the United States and Canada and, sometimes, in Australia and New Zealand as well, the term ounce has its origin in the Roman uncia. At the time, the ounce was defined as the twelfth part and the use of a copper bar served to define both the Roman pound and foot.
One of the things that you need to keep in mind is that the ounce never represented the same weigh in terms of grams. In fact, the French ounce was equal to 30.59 grams, the Dutch metric ounce was equal to 100 grams, the Spanish ounce was equal to 28.75 grams, among many others. The current definition of an ounce was adopted back in 1958 as we already mentioned at the beginning of this page.
Nowadays, the ounce still is a standard unit of mass in the United States Customary System of measurement. It is common to see it used for measuring food portions, packaged food products, postal items, among many others. While the ounce has some roots in the British history and culture, it is no longer officially used there. Nevertheless, the ounce is still used in some settings in the United Kingdom such as restaurants.
How Many Grams Are In An Ounce – The Formula
When you are trying to determine how many grams in an ounce, you will need to use a simple formula based on the ratio between the two units of measurement.
As we already told you, one ounce is equal to 28.34952 grams:
1 oz = 28.34952 g
This means that the mass in grams (g) is equal to the mass in ounces (oz) multiplied by 28.34952:
mass in g = mass in oz X 28.34952
So, let’s say that you want to convert 5 ounces to grams. All you need to do is to:
mass in g = 5 oz X 28.34952
mass in g = 141.7476 g
We can then state that 5 ounces = 141.7476 grams.

Practical Ways To Convert Ounces To Grams Manually
One of the things that you need to know about making conversions from ounces to grams is that you can use different methods. While we already showed you how you can easily use the ratio between the two different measurement units and calculate by hand as well as you can simply use our converter, we decided to show you some different methods. This way, you will be able to decide the one that you prefer.
No matter if you are stuck on a homework problem or if you are following a recipe, sometimes you need to make conversions to metric units. So, let’s see how you can easily do this by yourself and always get the right results.
Method #1: Make Quick Conversions
As we stated at the beginning of this page, 1 ounce = 28.34952 grams. However, it is quite understandable that you just won’t remember this number of grams. So, when you are trying to make some quick conversions from ounces to grams, you may simply use the ratio: 1 ounce = 28.35 grams.
So, let’s say that you are following a simple recipe and you need to convert 5 ounces into grams.
As we already showed you above, the mass in grams (g) is equal to the mass in ounces (oz) multiplied by 28.35. So, since you are trying to convert 5 ounces into grams, you will need to:
mass of grams = 5 ounces X 28.35
mass of grams = 141.75 grams
So, we can then state that 5 ounces = 141.75 grams.
In case you would be the more accurate and precise you can, you would then use the right ration where:
1 ounce = 28.34952 grams
So, in this case, and in order to convert ounces to grams, you would need to:
mass of grams = 5 ounces X 28.34952
mass of grams = 141.7475 grams
So, you would need to say that 5 ounces = 141.7475 grams.
As you can see, there isn’t really much of a difference between the two results and this is why so many people use the 28.35 grams instead of the 28.34952 grams.

Method #2: Converting Without A Calculator
Let’s say that you are in a middle of an exam and you just can’t use a calculator to convert ounces to grams. Or you may be at home preparing a recipe and you don’t have a calculator near you that you can use. In this case, this is probably the best method that you have to easily determine how many grams there are in a specific number of ounces.
So, let’s assume again that you want to determine how many grams there are in 5 ounces.
The first thing that you will need to do is to muliply this number of ounces by 30. So, basically, you will need to multiply 5 ounces by 3 and then just add a zero at the end result:
5 ounces X 30 = 5 ounces X 3 = 15 ounces, and then adding the zero at the end, you get 150 ounces.
Now, in this second step, you will need to calculate 10% of your answer. In case you don’t know, you just need to take off the zero at the end of the result that you got in the previous step.
So, following our example, 10% of 150 is 15.
In the next step, you will need to subtract half of 10% from your original answer.
If you remember the results we got:
Half of 15 = 15 / 2 = 7.5
And now, you will need to get the first result you got (240) and subract 7.5 from it:
150 – 7.5 = 142.5 grams
So, you can then state that 5 ounces = 142.5 grams.
If you check the previous method that we used to convert the same number of ounces (5) into grams, we got that 5 ounces = 141.7475 grams. As you can see, the result is pretty similar.
Method #3: Using A Conversion Ratio
In this last method we are going to use fractions to determine how many grams are in an ounce. While we understand that for some people this may be a difficult method, in some occasions it may be the best one to use.
So, in order to use this method, you will need to first write the value in ouncs as a fraction over 1. This means that the numerator of the fraction (the top part) will be the number of ounces and the denominator of the fraction (the bottom part) will be 1. Let’s say that you need to use 1.23 ounces of a specific ingredient. In this case, you will need to:
1.23 ounces / 1
Now, you will need to multiply this fraction you just write by (1 gram / 0.035 ounces). In case you are wondering about this ration, you just need to know that this is the conversion ratio that allows you to determine how many ounces are in a gram.
(1.23 / 1) X (1 / 0.035)
As you probably already know, in order to solve this calculation, you will need to: 1.23 X 1 = 1.23 and 1 X 0.035 = 0.035
So, you will end up with the fraction:
1.23 / 0.035 = 35.14 grams
As you can see, it wasn’t hard at all to determine how many grams there are in 1.23 ounces:
1.23 ounces = 35.14 grams
When You Need To Do Multiple Conversions
The truth is that there are many different conversions that you can make. And since each one has their own ratios, it may be difficult to remember all of them. So, let’s say that you just can’t remember how to convert ounces to grams. What can you do?
Assuming that you are still looking to convert the 1.23 ounces into grams, you may easily remember that:
1 pound = 16 ounces
1 kilogram = 2.2 pounds
1 kilogram = 1000 grams
So, you just need to arrange these rations in the form of a fraction so that you can determine how many grams there are in 1.23 ounces. Therefore, you would need to:
(1.23 ounces / 1) X (1 pound / 16 ounces) X (1 kilogram / 2.2 pounds) X (1,000 grams / 1 kilogram) =
= (1.23 × 1,000)/(16 × 2.2 ×) = 1,230/35.2 =
= 34.94grams
As you can see, this number of grams that we got was very similar to the one that we got when we used the right ratio between ounces and grams.
Conclusion
As you can see, it’s pretty easy to convert ounces to grams. Besides, since we believe it may be useful, we also took the time to show you how to convert ounces to grams as well. All you need to ensure is that when you are following a recipe, that you use the same measurement units. This is how you will get the best results over and over again.
