How to convert g to oz
The exact conversion factor between grams and ounces gives the formula ounces = grams ÷ 28.3495. One ounce is 28.3495 grams — the kitchen-scale conversion for baking recipes.
For a rough mental estimate, remember that 1 g = 0.0353 oz. To go the other way, see the ounces to grams converter — it uses the reciprocal factor.
Worked examples
Example: convert 28.35 g to oz. Apply the formula — ounces = grams ÷ 28.3495 — and you get 1 oz. Reverse-check it by using the ounces to grams to come back to 28.35 g; if you do not land on the original number, a factor was inverted.
Example: convert 1,000 g to oz. Apply the formula — ounces = grams ÷ 28.3495 — and you get 35.27 oz. Reverse-check it by using the ounces to grams to come back to 1,000 g; if you do not land on the original number, a factor was inverted.
Where the factor comes from
The pound used today is the international avoirdupois pound, defined since 1959 as exactly 0.45359237 kilograms. The kilogram itself was redefined in 2019 in terms of the Planck constant, so the chain of custody now runs from a universal physical constant down to your kitchen scale. Because both ends of the chain are exact, converting is pure arithmetic — the only rounding happens when a result is displayed.Common mistakes
Confusing mass and force. Pounds-force (lbf) and pounds-mass (lb) are different physical quantities. Recipes and body weight use mass — the factor on this page applies.
Avoirdupois vs troy. Gold, silver and gemstones use the troy ounce (31.103 g), which is about 10% heavier than the avoirdupois ounce (28.35 g) on this page.
Double rounding. kg → lb → oz in sequence compounds rounding error. Convert directly to the final unit in one step.
Quick mental shortcuts
Mental shortcuts: kg → lb ≈ ×2.2 (75 kg ≈ 165 lb); lb → kg ≈ ÷2.2; g → oz ≈ ÷30 (a 100 g chocolate bar is about 3.5 oz). For cooking, weigh once and remember: 1 stick of butter = 113 g = 8 tbsp.
