About Grams
The gram (g) is a unit of mass in the International System of Units (SI). A gram is 1,000th of a kilogram and 1,000th of a kilogram consists of 1,000 g and each kilogram of 1.000 kg =1 000 g. 1 g = 1,000 mg (milligrams)
Grams measure mass. Grams are often used to estimate things like quantity of food, number of ingredients, weight of small objects etc.
About Ounces
The ounce (oz) we commonly see in everyday mass measurements here in America is the avoirdupois ounce. One avoirdupois ounce is equal to precisely 28.349523125 grams.
Be careful not to confuse an ounce with a troy ounce. A troy ounce is a measure of weight that is mostly used with precious metals. A troy ounce measures out to nearly 31.1035 grams and shouldn't be used for a typical grams-to-ounces measurement unless your context warrants troy measures.

Grams to Ounces for Cooking
You often measure foods and other cooking and baking ingredients by grams or ounces. If you are using an ounce cooking scale for an ingredient specified in grams, just divide the amount in grams by 28.349523125 to convert grams to ounces.
For example, a recipe calling for 350 grams of an ingredient equates to approximately 12.35 oz. There are no other ingredient interactions involved in a mass-to-mass conversion.
Grams to Ounces for Food Packaging
You'll often see items on food labels in grams in addition to the same ounces sold here in the United States. Converting measurements to the same unit helps you compare different size packages.
For instance, a 250- gram package has an approximate weight of 8.82 ounces. A 500-gram package is roughly equal to 17.64 ounces, or 1.10 pounds.
Grams to Ounces and Pounds
For larger amounts the ounces can also be converted to pounds, as there are 16 avdp ounces to 1 lb, and 1 lb=453.59237 g.
Therefore:
Grams ÷ 453.59237 = Pounds
For example:
500 ÷ 453.59237 = 1.1023 pounds
So, 500 grams is approximately 1.10 pounds, or 17.64 ounces.
Exact vs. Rounded Grams to Ounces Values
The conversion factor between grams and avoirdupois ounces is defined exactly:
1 oz = 28.349523125 g
To one practical level, this is commonly given as 28.35 grams to an ounce. By extension, 1 gram is frequently stated as being 0.035274 ounces. Using the exact multiplier in calculations before rounding the end result is numerically more accurate.
When to Use Troy Ounces
Do not rely on the everydayavoirdupoisounceif it saystroyounces specifically. Many troy ounces measure precious metals (including gold, silver, platinum and palladium).
1 troy ounce ≈ 31.1034768 grams
Thus, gram to troy ounce conversion is not same as normal gram to ounces. Always make sure the type of ounce before you convert.
Tips for Accurate Grams to Ounces Conversions
Use 28.349523125 grams per avoirdupois ounce for standard mass conversion.
Do not use a volume conversion such as cups, tablespoons, or milliliters for this calculation.
Keep additional decimal places during the calculation and round the final result.
Use troy ounces only when the measurement specifically concerns troy weight.
For recipes, remember that grams and ounces in this conversion refer to mass, not fluid ounces.
Grams vs. Fluid Ounces
Grams to ounces and grams to fluid ounces Conversion Converting from grams to ounces and grams to fluid ounces are not the same process. Grams represent volume while a fluid ounce represents amount of space it takes up.
For instance, 100 grams of water and 100 grams of oil weigh the exact same but will not exactly fill the same volume. Thus the factor commonly used for grams to fluid ounces should not be applied here (which normally amounts to 28.349523125).
