How to convert ounces to grams
Multiply ounces by 28.35 to get grams, or divide grams by 28.35 to get ounces. This is a pure weight conversion, so it works identically for every ingredient — 4 oz of flour, sugar or chocolate is always about 113 g.
Common values
- 1 oz = 28 g
- 4 oz (¼ lb) = 113 g
- 8 oz (½ lb) = 227 g
- 16 oz (1 lb) = 454 g
Note that fluid ounces measure volume, not weight — this converter is for weight ounces only. For liquids, use the grams-to-milliliters tool instead.
Worked example: 6 oz of chocolate to grams
One ounce is 28.35 g, so multiply 6 × 28.35 = 170.1 g, rounded to 170 g. This is a pure weight conversion, so 6 oz of flour, sugar or chocolate is always about 170 g.
Frequently asked questions
How many grams is 1 ounce?
1 ounce is 28.35 g. For quick mental math, round to 28 g per ounce — the error is under 2% and rarely matters in home cooking.
How many grams is 8 ounces?
8 oz is 227 g (half a pound). 16 oz is 454 g (one pound), and 4 oz is 113 g (a quarter pound).
Are fluid ounces the same as weight ounces?
No. Fluid ounces measure volume and weight ounces measure mass. This converter handles weight ounces only. For liquid volume, use the grams-to-milliliters tool.
Does the ingredient matter for ounces to grams?
No. Because both ounces and grams measure weight, the conversion is the same for every ingredient — 1 oz is always 28.35 g.
How do I convert pounds to grams?
1 pound is 16 oz, so it is 453.6 g. Enter 16 in the ounces field to get 454 g, or multiply pounds by 453.6 directly.
Why do European recipes use grams instead of ounces?
Grams are metric and scale cleanly (1000 g = 1 kg), which is easier for scaling and more precise than fractional ounces. Most digital kitchen scales switch between the two.
