how many cups is in...310g(11oz) of FLOUR & SUGAR?

There are lots of conversion tables online, because of course it depends on what it is.

310 grams of flour is 2 and 1/2 cups

310 grams sugar is 1 and 1/2 cups

1 1/2 cup is NOT ONE1/2 cup, but rather one AND one half cups. So essentially, you put more sugar in the recipe than you did flour. You need to fill up the cup, level off, and then fill the cup again up to the 1/2 mark, or use a 1/2 cup measuring cup. So that is why your cake was so sweet. You did not know how to read a recipe. You will learn. AND...Of course, you can use the same measuring cups. How ridiculous, all of these people telling you to buy two different sets. The only difference is fill the liquid to almost overflowing (when the top looks like it is slightly higher than the edge of the cup), and dry ingrediants should be scraped level with the back of a butter knife. Same for measuring spoons. Liquid to overflowing and dry scraped level. The other people who answered are purists but it is not necessary. Enjoy yourself and don't make it any harder than it has to be. Only thing is READ THE RECIPE AND FOLLOW EXACTLY, and in the order it tells you to do things. Do not skip ahead or add everything at once unless it tells you to. It is chemistry, afterall.

According to google its 1.375 cups which when rounded to the closest tenth (not ten) is 1.4 cups or 1 cup and 4/10 of a cup or 1 cup and 2/5 of a cup

Its all the same
