How to Convert Ounces to Grams?

Converting any weight to another unit of weight is not a difficult task if you know the value of the units that you have to convert. Furthermore, this case is also the same if you know the conversion value of one ounce then you can easily convert ounces to grams.

What is Ounce?

An ounce is a unit that we use to measure weight. Primarily we use it the United States to measure the packaged food. In addition, there are several other uses of ounce currently. That is:

• Troy Ounce – That we use to measure the value of precious materials like gold, silver, etc. Furthermore, its weight is around 31.1 g.
• Ounce Force – It is the measure of weight.
• Fluid Ounce – That we use to measure volume.

What is Gram?

A Gram is an international system of the unit (SI unit) that we use to measure weight. Besides, it is the most common unit that we use to measure the weight of the object. Generally, the nutrition value mentioned in the packs of goods is in grams or percentage of weight in gram.

Methods to Convert Ounces to Grams –

• Method 1 – Quick Conversion
• Method 2 – Converting without a calculator
• Method 3 – Using the conversion ratio

Let us see all the methods in detail below –

Method 1: Quick conversion

For this firstly you should know the value of grams per ounce (28.35 g) after knowing the value of gram per ounce you can easily find the value of gram by simply multiplying the value of gram per ounce with the value of ounce.

Gram = number of ounce × per ounce weight of a gram
Gram = number of ounce × 28.35
Example: Suppose the weight of a chicken is 42 ounces (oz.) and you have to convert it into gram then
Gram = number of ounce × 28.35
Gram = 42 × 28.35 = 1190.7 grams or 1190.7 g

Method 2: Converting without a calculator

If you are stuck in a situation where you do not have a calculator to convert the value of ounces to grams then use this method. Furthermore, this method tells an approx. value, which is close to the original value.

Firstly, in this method, multiply the value of ounce with 30. Then find the 10% of that value. After finding the 10% value divide the value by 2 and then subtract it from the value of the product of ounce into 30.

Example: Suppose in the above example you do not have a calculator then do as described in this method.

Gram = 42 × 30 = 1260
10% of 1260 = 1260 × 10/100 = 126
126 ÷ 2 = 63
1260 – 63 = 1197

This answer is not correct but the value is approximately close to the answer.

Method 3: Using the conversion ratio

This method is a little tough as it uses a fraction. Firstly, take an ounce unit as the numerator and in the denominator write 1. Secondly, multiply it by 1 in numerator and 0.035 in the denominator (weight of one gram in an ounce).

Thirdly multiply the numerators and denominators after canceling the common units. Finally, divide the result and you will get the answer.

Example: consider the example mentioned in method 1. And solve it according to this situation then

42 ounces ÷ 1 × 1 ÷ 0.035 ounces
42 ÷ 1 × 1 ÷ 0.035
42 ÷ 0.035 = 1200

Which is approximately close to the real value.
