Frequently Asked Questions
How do I convert grams to ounces?
Multiply the gram value by 0.0352739619. For example, 100 g × 0.0352739619 = 3.527 oz.
Is this ounce the same as a fluid ounce?
No. This page converts mass (grams to avoirdupois ounces, used for weighing solids). A fluid ounce measures volume, not weight, and the two aren't interchangeable except for substances with a known density.
How many grams are in an ounce of a cooking ingredient?
1 oz = 28.349523125 g exactly, regardless of ingredient, since this is a mass conversion, not a volume one. Note that cooking ingredients are sometimes measured by volume (cups, tablespoons) instead, which does depend on the ingredient's density.
