Grams to ounces for recipes and product weights
Use this mass conversion for ingredients, parcels, and product labels. It deliberately distinguishes the ordinary avoirdupois ounce from fluid ounces and precious-metal troy ounces.
Formulas in both directions
oz = g ÷ 28.349523125g = oz × 28.349523125Divide grams by exactly 28.349523125. The reciprocal is approximately 0.03527396195 oz per gram.

Worked real-world examples
Example 1
A bread recipe calls for 125 g of flour. Convert that mass for a scale set to ounces.
125 ÷ 28.349523125 = 4.409245244125 g = 4.409245244 ozExample 2
A coffee bag contains 500 g. Convert the net mass for an ounce-based product comparison.
500 ÷ 28.349523125 = 17.63698097500 g = 17.63698097 ozWhat the units mean
gram (g)
A gram is one thousandth of a kilogram. It is convenient for food ingredients, medicine labels, small parcels, and laboratory mass.
avoirdupois ounce (oz)
The avoirdupois ounce is one sixteenth of an international pound and equals exactly 28.349523125 grams.
Where these units are used
Grams are the usual small-mass unit in metric countries. Ounces remain common on US food, mailing, and retail labels, and in recipes written for US audiences.
Important distinctions
An oz here is a mass ounce. A US fluid ounce measures volume, and a troy ounce used for precious metals equals about 31.1034768 g. Do not substitute one for another.
Accuracy and rounding
Cooking often needs one or two decimal ounces; postal and laboratory work should follow the scale resolution. Preserve extra digits until the final rounding step.
Frequently asked questions
How many ounces are in 100 grams?
100 g is approximately 3.5274 avoirdupois ounces.
Does oz mean fluid ounces here?
No. This is a mass conversion. Fluid ounces require the ingredient's volume and, for mass, its density.
Can I use this for gold or silver?
Precious metals are commonly quoted in troy ounces, not avoirdupois ounces, so use a dedicated troy conversion.
How many grams make one regular ounce?
One avoirdupois ounce is exactly 28.349523125 grams.
