Grams and ounces are two different units of mass. The gram is a worldwide unit of measurement in the metric system; however, the ounce is an imperial unit and is widely in use in the United States. For this reason, it is sometimes helpful to be able to convert from grams to ounces.

Multiply the number of grams by 0.0352739619 with a calculator.

Use the correct number of significant figures in your answer to be scientifically precise. You can find this by counting the number of digits in the original grams measurement. If zeroes come after the number, they only count as significant figures if there is a decimal point. For example, 30,300 has three significant figures, and 3,030.0 has five.

Remember to include the correct units identifier -- for example, 15 oz.
