If you're wondering how much 200 grams is in a cup, the answer is about 3/4 of a cup. To be precise, 1 cup is 240 grams, so 200 grams is 80% of a cup.
This information can be useful when you're cooking or baking and need to convert measurements. For example, say a recipe calls for 2 cups of flour, but you only have 1 1/2 cups on hand. You know that 1 1/2 cups is equal to 360 grams, so you would need to use 300 grams of flour (3/4 of a cup plus half of another).
Similarly, if you have 200 grams of sugar and want to know how many cups that equals, simply divide by 240 (200 divided by 240 = 0.83). So in this case, 200 grams would be just under 1 cup.
