Gram (g) is a weight and mass measurement unit, while ounce (oz) is another unit to measure the mass, volume or weight of an object or liquid. You may need to convert gram to ounce when you are checking the nutrition tables of the foods or while cooking when you need to measure the ingredients.

Grams (g) to ounces (oz) conversion can be done easily if you know the right formula. In this blog, we will learn how to convert g to oz, the relation between these two measurement units and the history of these units. Furthermore, we will understand the conversion procedure with the help of examples and understand the difference between them. Let us begin by learning how to convert grams to ounces.

Convert From Grams To Ounces 

We can easily convert gram to ounce once we know the mathematical relation between these two measurement units. 1 gram is 0.035274 oz which can be rounded to 0.0353 oz.

1 Gram = 0.0353 Ounces

1 Ounce = 28.3495 Grams

So if we want to convert g to oz, we need to multiply the given value in grams by 0.0353 to get the value in ounces. Isn’t it simple? Let’s have a look at the mathematical formula and convert g to oz with the help of examples.

Grams To Ounces Formula For Easy Conversion

Now that we know one Gram equals 0.0353 ounces, let us learn the grams-to-ounces formula. This will make any grams to ounces conversion easy.

The formula to convert gram to ounce is:

1 Gram = Ounce x 0.0353

Therefore, if you wish to convert any value of grams in ounces, you need to multiply the value by 0.0353 to get the appropriate value in ounces.

Examples of Converting Grams To Ounces

Let us learn how to convert g to oz with the help of five examples.

Example 1: Convert 20 Gram to Ounce

When we use the formula, we get

20 g = (20 x 0.0353) = 0.7054 oz

Hence, 20 g is equal to 0.7054 oz

Example 2: Convert 150 grams to ounces

Use the formula, and we will get,

150 g = 150 x 0.0353 = 5.29109 oz

Thus, 150 g is equal to 5.29109 oz

Example 3: Convert 238 grams to ounces

By using the same conversion formula, we get

238 g = 238 × 0.0353 = 8.3952 oz

Therefore, 238 grams is 8.3952 ounces.

Example 4: Convert 1200 g to oz

Here, 1200 g = (1200 x 0.0353) = 42.32875 oz

Hence, 1200 g is equal to 42.32875 oz.

Example 5: Convert 2400 grams to ounces

Here, 2400 grams = (2400 x 0.0353) = 84.65751 oz

Thus, 2400 grams is equal to 84.65751 ounces

Gram – Definition

A gram is a measuring unit used to measure weight and mass. It is also used to measure lighter non-liquid objects. As per the International System of Units (SI), this mass unit is used globally. The gram (g) definition is based on another weight measurement unit, kilogram (kg). Gram is one-thousandth part (1/1000) of a kg.

  • What is The Current Use of Gram?

Grams are globally accepted as the weight measurement unit. Non-liquid items less than one kg are generally weighed in grams. We notice that the weight of pulses, vegetables or fruits is written as 100 g, 250 g or 500 g. Moreover, the packed products add a nutrition label for every 100 g of the respective ingredient.

  • What is The History of Gram?

The word ‘gram’ is derived from the French word ‘gramme’ and the Latin word ‘gramma’; both these words mean small in weight. Originally, a gram was termed the absolute weight of water in a cubic centimetre at the temperature of melting ice. It was used as a fundamental unit of mass and part of centimetre-gram-second (CGS) systems of units. However, with the widespread adoption of SI, kilograms became the base unit of mass, and the Gram was later redefined as 1/1000th of a kilogram.

Ounce – Definition

It is a unit of mass in the imperial and US customary measurement systems. It is another unit to measure an object or liquid’s mass, volume or weight. Ounce units can be classified into dry ounces and fluid ounces. A dry ounce is the smallest measurement unit usually used for measuring dry cooking ingredients like nuts, seeds etc. A fluid ounce is denoted as fl oz and is normally used for measuring the volume of liquid items like milk, honey, oil etc.

  • How is Ounce Used?

This unit is mostly used in the US to measure packaged food items, portions, postal items, etc. After adopting metrication, the United Kingdom (UK) has stopped using ounces, but you may still come across this measurement unit in some restaurants.

  • What is The History of Ounce?

An ounce is derived from an Ancient Roman measurement unit termed uncia. The abbreviation oz was taken from the Italian word ‘onza’. A standardised copper bar defined the ounce, similar to the Roman pound and foot. This copper bar was divided into twelve equal parts and was termed unciae. The ounce has been used as a standard unit of mass throughout different applications. For instance, the Dutch metric ounce was 100 g, the French ounce was 30.59 g, and the Spanish ounce was 28.75 g.

Understanding The Gram-Ounce Relationship

We can determine the relationship between grams and ounces with the help of mathematics. There exists a formula for converting grams to ounces and vice versa. To understand this formula, we must learn the basic values, which are as follows:

1 Gram = 0.0353 Ounces and 1 Ounce = 28.3495 Grams

Now you can use the formula Gram = Ounce x 0.0353 to get the respective value in ounces. You can also use a grams-to-ounce calculator or an online converter to get the desired values in a fraction of a second.

Abbreviations For Grams and Ounces

Gram is often abbreviated as ‘g’ or ‘gm’, while ounce is ‘oz’. You may come across these abbreviations when you refer to the grams-to-ounces chart. Moreover, when you use an online converter to determine grams to ounces or vice versa, you may see these abbreviations written after the values.
