Grams To Oz Calculator
Free grams to ounces converter
Converting a recipe, a package weight, or a nutrition label between metric and US units? This free tool converts grams to ounces or ounces to grams instantly, and also reports the same weight in pounds, kilograms, and milligrams so you rarely need a second converter. It uses the international avoirdupois ounce, the everyday ounce on US food labels and postage scales.
How to convert grams to ounces
One avoirdupois ounce is defined as exactly 28.349523125 grams, so the conversion is a single multiplication: ounces = grams × 0.035274. Going the other way: grams = ounces × 28.3495.
Worked example: a recipe calls for 500 g of flour. Multiply: 500 × 0.035274 = 17.6370 oz. The tool also shows this as 1.1023 lb, 0.5000 kg, and 500000.00 mg. Reverse check: 16 oz × 28.3495 = 453.5920 g, exactly one pound.
Quick reference table
Handy values for cooking and shipping:
1 g = 0.0353 oz
5 g = 0.1764 oz
10 g = 0.3527 oz
25 g = 0.8818 oz
50 g = 1.7637 oz
100 g = 3.5274 oz
250 g = 8.8185 oz
500 g = 17.6370 oz
1000 g (1 kg) = 35.2740 oz
Everyday weights to anchor your intuition
A paperclip or a US dollar bill weighs about 1 gram. A pencil is around 7 g, an AA battery about 23 g, a tennis ball about 58 g, and a medium apple about 182 g (roughly 6.4 oz). If your converted number looks wildly off next to these anchors, double check whether you entered grams or ounces.
Avoirdupois vs troy ounces
This tool uses the avoirdupois ounce (28.3495 g), the standard for food, mail, and general commerce. Precious metals use the troy ounce (about 31.1035 g), which is nearly 10 percent heavier. If you are converting gold or silver weights, use a troy-ounce converter instead, because this one will understate the value.
Choose your precision
The result now lets you pick 0 to 8 decimal places. Cooking usually needs 1 or 2 (250 g = 8.82 oz at 2 decimals); lab work may want 6 or 8. The default is 4, the same precision the converter has always shown.
Step-by-step working under every result
Each conversion now shows its substitution: the factor used, the multiplication, and a reverse check. For 250 g: 250 x 0.035274 = 8.8185 oz, and the check 8.8185 x 28.3495 lands back at 250.0001 g, confirming the factor pair is consistent.
