Grams (g) to Ounces (oz) Conversion
Grams
The gram is a unit of mass equal to one thousandth of a kilogram (10⁻³ kg) and is the standard unit for small masses in chemistry, pharmacy, food science, and nutrition. In the CGS system, the gram was the fundamental unit of mass. In nutrition, all macronutrients — carbohydrates, proteins, and fats — are quantified in grams per serving.
Ounces
The ounce (avoirdupois) is a unit of mass equal to exactly 28.349523125 grams, or one sixteenth of a pound, used in the United States and United Kingdom for food portions, postal weights, and product labelling. It must be distinguished from the troy ounce (31.1035 g), used exclusively for precious metals, and from the fluid ounce, which is a unit of volume.

How do I convert grams to ounces?
Multiply grams by 0.035274 to get ounces. The exact factor is derived from 1 oz = 28.349523125 g. Quick cooking references: 28 g ≈ 1 oz, 100 g = 3.527 oz, 113 g = 4 oz (¼ lb), 227 g = 8 oz (½ lb), 454 g = 16 oz (1 lb). This conversion is most common in recipes — a US recipe calling for "8 oz of butter" equals 227 g, while "3.5 oz of chocolate" equals about 100 g, which is a standard chocolate bar.
What is the difference between a weight ounce and a fluid ounce?
A weight ounce (oz avoirdupois) measures mass — 1 oz = 28.35 g. A fluid ounce (fl oz) measures volume — 1 US fl oz = 29.574 mL. They are completely different units. Water happens to make them close: 1 US fl oz of water weighs about 29.57 g (slightly more than 1 weight oz). But for denser liquids the difference is significant: 1 fl oz of honey (density ≈ 1.4 g/mL) weighs about 41 g. In recipes, "4 fl oz of milk" and "4 oz by weight" are not the same measurement.
