Grams to Ounces Converter: g to oz Chart and Formula

This chart covers the gram amounts people convert most, from 1 gram to 1 kilogram. The middle column gives ounces to 2 decimals for a digital scale. The last column rounds to the nearest 1/4 ounce, the way most recipes write ounces.

100 grams to ounces is 3.53 ounces, or about 3 1/2 ounces on a kitchen scale. That is why a 100 gram chocolate bar is often labeled 3.5 oz. European nutrition labels list values per 100 grams, so this conversion helps when you compare foods.

200 Grams and 50 Grams in Ounces

200 grams is 7.05 ounces, which most scales show as 7 ounces. 50 grams is 1.76 ounces, close to 1 3/4 ounces. Both follow from 100 grams: 200 grams is twice 3.53 ounces, and 50 grams is half.

Package Sizes in Grams and Ounces

US packages often print both units on the label. These pairs explain many gram amounts people look up, like 113, 227 and 340 grams. Labels round to whole grams.

To change ounces to grams, multiply the ounces by 28.35. This chart covers common recipe and package amounts. Values are rounded to 2 decimal places.

Pounds, Ounces and Kilograms

One pound is 16 ounces, or 453.6 grams. One kilogram is 35.27 ounces, which is 2 pounds 3.27 ounces. For a large gram amount, divide by 453.6 to find whole pounds, then convert the grams left over to ounces.

An ounce (oz) measures weight, while a fluid ounce (fl oz) measures volume. One US fluid ounce holds 29.57 ml (NIST). For water, 1 fluid ounce weighs about 29.6 grams, a little more than 1 ounce of weight. For other foods the gap is much bigger, so 8 fluid ounces (1 cup) of flour weighs only about 4.2 ounces. If your recipe lists fluid ounces, use the cups to ml converter instead.

Troy Ounces for Gold and Silver

Gold, silver and other precious metals are weighed in troy ounces. A troy ounce is 31.10 grams, about 10 percent heavier than a regular ounce (Ounce). Do not use troy ounces for food or kitchen scales.

To convert g to oz, divide the grams by 28.35. You can also multiply the grams by 0.03527, which gives the same answer. To go back from ounces to grams, multiply the ounces by 28.35.

Worked Example

For 250 grams, 250 ÷ 28.35 = 8.82 ounces. Rounded to the nearest 1/4 ounce, that is 8 3/4 ounces. For 6 ounces, 6 × 28.35 = 170.1 grams.

Quick Mental Math

Every 100 grams is about 3 1/2 ounces, and every ounce is about 28 grams. So 300 grams is about 10 1/2 ounces, close to the exact 10.58 ounces. Use the calculator when you need the exact number.

Tips for Weighing in Grams and Ounces

A kitchen scale makes either unit easy. These habits keep your readings accurate. Each one fixes a common mistake.

• Use the unit button. Most kitchen scales switch between grams and ounces, so you can read the weight in whichever unit your recipe uses.
• Press tare first. Set the bowl on the scale and zero it before you add food.
• Pick grams for small amounts. A gram is a much smaller step than an ounce, so grams give finer readings for yeast, salt and spices.
• Check for fl oz. If the recipe says fluid ounces, measure volume with a liquid cup, not weight on a scale.
• Round to 1/4 ounce. Most recipes that use ounces round to the nearest 1/4 ounce, so you do not need 2 decimals.
