Weight and Mass / g → oz
Convert Grams to Ounces
Compare mass in kilograms, pounds, grams, and ounces. Pounds and ounces use avoirdupois definitions. Convert Grams (g) to Ounces (oz). Find the formula, worked examples, unit definitions, and practical guidance below.
How to convert grams to ounces
These units measure mass. Converting recipe weights to cups requires an ingredient-specific density; the same volume of flour and water will not have the same mass.
Use x for the value in g, b for the intermediate value in kg, and y for the result in oz.
oz = g × 0.001 ÷ 0.028349523125
Worked examples
10 g ≈ 0.352739619496 oz
Step 1: (10 × 0.001) ≈ 0.01 kg.
Step 2: 0.01 ÷ 0.028349523125 ≈ 0.352739619496 oz.20 g ≈ 0.705479238992 oz
Step 1: (20 × 0.001) ≈ 0.02 kg.
Step 2: 0.02 ÷ 0.028349523125 ≈ 0.705479238992 oz.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Grams
A gram is one thousandth of a kilogram. Recipes and small packages often use grams. A gram measures mass, not liquid volume.
About Ounces
An avoirdupois ounce is one sixteenth of an avoirdupois pound. It measures mass; a fluid ounce measures volume, and a troy ounce is a different mass unit.
Definitions and sources
Use mass units consistently
Pounds and ounces here are avoirdupois units: 16 ounces make one pound. Enter 8 pounds 8 ounces as 8.5 pounds, rather than 8.8 pounds. Precious metals may use troy ounces, which are not included here.
A weight conversion preserves mass. It cannot tell you how many cups an ingredient fills without knowing its density and how it was measured. Use a kitchen scale when a recipe specifies mass.
Keeping ingredients in the same mass unit also makes it easier to compare quantities in recipe calculations.
