The grams-to-ounces formula
To convert grams to ounces, multiply the weight by 0.03527. So 1 g = 0.03527 oz, and going the other way, 1 oz is about 28.35 g. A few worked examples: 100 g of flour is 100 × 0.03527 = about 3.53 oz; 250 g of sugar is about 8.82 oz; 500 g of butter is about 17.64 oz. A full kilogram (1000 g) works out to roughly 35.27 oz. The 'ounce' here is the avoirdupois ounce, the everyday unit on US food labels, recipes, and shipping scales.
Where you'll actually use it
This conversion shows up most when you're cooking from a US recipe, since American cookbooks and packaging list weight in ounces. A stick of butter is 4 oz (about 113 g), and a bag of coffee beans is often sold as 12 oz (about 340 g). Meanwhile, kitchen scales outside the US read in grams, so you're constantly translating an ounce figure into grams, or checking the grams on your scale back against a recipe. It's also handy for reading the oz weight printed on an incoming parcel and picturing it in grams.
Two traps to avoid
First, the 'ounce' used for gold and silver is not this one — it's the troy ounce, where 1 troy oz is about 31.10 g. If you price precious metals with 28.35, you'll be off by roughly 10%. Second, a weight ounce (oz) and a fluid ounce (fl oz) are different animals: fl oz measures volume, so you can't convert it to grams without knowing the liquid's density. And remember that 0.03527 is rounded — for precise work, use more digits (0.035274).
Frequently asked questions
How many ounces is 100 grams?
100 g is about 3.53 oz — just multiply 100 by 0.03527. For reference, 50 g is about 1.76 oz and 200 g is about 7.05 oz.
Can I use this to weigh gold or silver?
No. Precious metals are measured in troy ounces, and 1 troy ounce is about 31.10 g — heavier than the standard (avoirdupois) ounce of 28.35 g. This g→oz tool is for everyday weight like food and parcels.
In recipes, is 4 oz the same as 4 fl oz?
Not usually. An ounce (oz) is weight; a fluid ounce (fl oz) is volume. Water is close because its density is near 1 (4 fl oz is about 118 g), but ingredients like flour or honey have different densities, so the two can diverge a lot.
