Frequently Asked Questions
My recipe says 3.5 oz of butter — how much is that in grams?
3.5 oz = 99.2 g, so use 100 g. Common US recipe amounts: 1 oz = 28 g, 2 oz = 57 g, 4 oz = 113 g, 8 oz = 227 g. US butter sticks are 4 oz (113 g) each — a useful anchor point when converting baking recipes.
Are ounces always a weight measurement?
In this converter, yes. However, fluid ounces are different and measure volume, not weight. One US fluid ounce equals approximately 29.5735 ml.
Can I round grams to ounces for cooking?
For everyday cooking, light rounding is fine. For precise baking, where flour and sugar ratios matter, use accurate values. A 5% error in baking can change texture and rise significantly.
Why do recipes mix grams and ounces?
Recipes often come from different measurement traditions. US recipes use ounces and pounds, European recipes use grams and kilograms.
My kitchen scale only shows grams — how do I measure US recipe ounces?
Multiply the ounce value by 28.3495 to get grams. So 3 oz = 85 g, 6 oz = 170 g, 12 oz = 340 g. Most digital kitchen scales switch between grams and ounces via a unit button — check the underside or manual. When baking, set the scale to grams and use converted amounts directly rather than estimating.
