Is there a conversion sight US to grams for recipes
Hi Glenda! King Arthur has a great searchable chart for this: https://www.kingarthurflour...
This is a great chart. I use it all the time.
This is a bit of a confusing question, as cups are a volume measure while grams are (strictly speaking) a measure of mass; a gram is equivalent to a cubic centimeter of water- a cup will hold approximately 250cc (=250 ml) of water= 250 grams. For other ingredients you would need to know their specific density, which presumably the chart mentioned above will give for common baking ingredients.
